Forbes have published their latest list of the planet's richest people, and have declared Valve co-founder Gabe Newell the Newest Video Game Billionaire. Of the 1226 billionaires on the planet, Newell is the 854th richest with an estimated worth of $1.5 billion.

Valve keep their finances strictly private, so Forbes consulted "video game industry insiders, equity analysts, investment bankers, and technology analysts" for figures and factored in the tremendous success of Portal 2 and the continued growth of Steam as factors in their latest estimate.

"Even the most conservative estimates put Valve’s enterprise value at more than $3 billion," they say. Newell owns more than half of Valve, placing his estimated worth at the 1.5 billion mark.

Well done them. That is rather a lot of cash. They could probably pool all their resources and create a working Portal gun if they wanted to, but they'd probably rather make games.

Writing a regular column about free games has been one of the most transformative jobs I've ever taken. Buried away in the depths of the internet are some remarkable things, and being able to unearth them, then share them with a huge number of like-minded people, is always an absolute pleasure.

It's also changed the way I think about games, changed the way I write about games, and even inspired me to make games. All this from spending one day a week playing mostly amateur creations then scrawling down some words about what I made of them.



I've played some fantastic games while preparing these columns. Nous, a fascinatingly dark abstract shooter that poses as a personality-evaluating AI, was one of the more intriguing ones. It's a game that spins an unnerving story through its only character, who flits worryingly between help and harm. It's immaculately presented, and alternately amusing and sinister. A real gem.



Or how about Wonderputt? It's a crazy golf game among the most delightful freebies I've ever seen. It presents an ever-changing landscape, a world that morphs around you as you progress through its 18 holes, and one of the most fabulously animated things. It only lasts about 15 minutes, but I spent that time with my face fixed into a grin.

For absolutely no pennies, you can experience things unlike anything else in our medium. Take Terry Cavanagh's At a Distance, a co-op game that asks two players to sit on a local network, exploring an abstract maze, making changes to each other's versions of the world as they work to solve its ultimate puzzle. Haunting and abstract, it's a fascinating look at how we can work together within games in new and exciting ways.

The Snowfield, too, is an experimental game. In it, you explore a harrowing wartorn environment, a place where the snow continues to fall and haunting sounds emit from its farer reaches. Soldiers who are still standing walk among the dead bodies, crying. It's not polished, but it's utterly affecting.



And, more recently, Unmanned's split-screen dialogue-choosing and mundane-task-completion contrasted stunningly with the more hard-hitting elements of its storyline. Its central character is often unpleasant - a liar and a cheat and a racist, if you let him be - but the questions it asks you as a player go far beyond those that are a part of the game itself.

Then there's been the bigger games. Portal was free for a while (it's currently just £7). World of Warcraft got a stripped-back free-to-play version. Team Fortress 2 went almost entirely free as it continued to expand, and Bungie's Marathon trilogy turned up without charge. That even the major studios occasionally give us something for nothing is a lovely thing: it might often be a smart business decision, advertising other titles or enticing in new players, but it still presents us with opportunities to try out some truly special releases without stretching our wallets.

Perhaps most importantly to me, I've spent time delving into the Adventure Game Studio community. AGS is a free-to-use game engine that's powered a number of commercial games, such as Time Gentlemen, Please! and Gemini Rue, but it's also the tech behind a huge number of free releases created as projects of passion. Being astonished by the quality of Keys of a Gamespace, Egress and Donna: Avenger of Blood inspired me to make my own game - Masked - in AGS. And I'm currently working on an even bigger project that utilises it.



I've revisited older games and I continue to find new ones. Spelunky is still, I genuinely believe, one of the best games available on PC - a free roguelike platformer with an stupidly ruleset and a fascinating environment to explore and destroy. Digital: A Love Story is an indie adventure set in the late 1980s, and sees your teenage character embark on a touching journey of discovery. And the terrifying but brilliant Dwarf Fortress recently got an enormous update.

This week, Flatland: Fallen Angle turned up with the best name in the world and a minimalist, noir-esque vibe. It's a game in which you play as a triangle on the run in a two-dimensional city. (Its 'Appreciation Version', which functions on a pay-what-you-like model, recently fell foul of PayMate - who cancelled and refunded all orders without notice, deciding only to inform the developers afterwards that they don't work with games because 'teenagers steal their parents' credit cards to buy them'.) Meanwhile, Russian Subway Dogs sees your canine character scurrying around the underground picking up scraps of food, fighting with other dogs, and - most importantly, of course - exploding bottles of vodka.

This is my last free games column for PC Gamer, but those fantastic free games won't stop coming, and I'm sure PC Gamer will continue to write about them.



Recently, I interviewed some developers as part of a feature I was writing. I wanted to find out why, when they are clearly such talented designers, artists and programmers, they persist in giving away their creations and asking for no money in return. Some of them worked full-time in the games industry and made their freebies on the side. For others, it was just a hobby. But one thread ran through every one of their answers: games are awesome, we love making them, and we want as many people as possible to benefit from that.

In what can often be a cynical industry, these developers are quite remarkable people. Long may their fabulous work continue.

Thanks for reading, folks.

We've seen some impressive fan-made Portal guns in the past, but they've been rare, costly one-off projects. Valve are giving us the chance to get hold of our own Aperture Science Handheld Portal Devices without having to burn ourselves horribly putting together an injection mould. Joystiq mention that, at Valve's request, toy manufacturers, NECA have put together a life-sized Portal gun. It'll hit the shops this summer with a $130 price tag attached.

There will be lights and those lights will change colour, but will it make the "pwung" noise? There's only one way to find out, and that's to buy at least five. Perhaps ten. Maybe more. More. MORE.

NECA will also be releasing a line of Left 4 Dead, Team Fortress 2 and Half-Life action figures, a few of which were shown off at the NYC Toy Fair. The Team Fortress 2 wiki has a snap of the new figures, you'll find that below along with a few shots of that Portal gun. Baggsy the Heavy.

Quantum Conundrum is being developed by Portal creator Kim Swift. It's a first person puzzler in which you play a twelve your old boy lost in his mad scientist uncle's underground laboratory. It's full of safes, switches, lava and vast gaps with no bridges. This would be a serious problem but for the fact that you can switch between five dimensions, each of which affects matter differently. By switching between world on the fly, otherwise immovable objects like safes can be tossed, stacked and even surfed to make it past the mad machines and laserbeams that every mad scientist installs in their homes as standard. It's all demonstrated perfectly in the walkthrough video above from Gametrailers, spotted on RPS. It's out early this year, and looks rather good, don't you think?

Crysis 2 was the most pirated game last year, with nearly four million illegal downloads according to a report on Torrent Freak. The numbers were collated from stats put out by public BitTorrent trackers, and suggest a slight decrease in overall piracy numbers compared to 2010.

Crysis 2 was released in March, so it's had plenty of time to reach the 3,920,000 downloads mark. Call of Duty: Modern Warfare 3, released in November, was the second most pirated game, with around 3,650,000 illegal downloads. Battlefield 3 was a close third at 3,510,000 downloads. Fifa 12 took fourth place with 3,390,000 downloads. Portal 2 was fifth with 3,240,000.

Those are some rather huge numbers, sadly, and around three times bigger than the most pirated console titles. They're slightly smaller than last year's round-up. It'd be nice if that was the start of a general downward trend, but PC piracy will continue to be a big concern for publishers in the coming year.

In most co-operative games, players don’t work together so much as work beside one another. The closest you’ll get to real teamwork is pulling the trigger at the same time. Portal 2 doesn’t work that way. Its co-op problems are impossible without a friend, and each reality-twisting solution forces you to share a brain.

My brain is neurotic, and though he hopefully never noticed, playing with Tom was competitive, too. Every time he worked out the solution first, it stung. Every time my suggested solution turned out to be wrong, I was convinced he thought I was an idiot. The problem is that you’re never just wrong in Portal 2, your idea is stupid, deadly and physically impossible.



Thank god it’s also funny. In singleplayer, Portal 2 is a finely scripted sitcom starring a woman, a robot and a potato. In co-op, it’s a slapstick buddy comedy, with both players as comic foil and GLaDOS as your straight man. When either of us would screw up, Tom and I wouldn’t yell or criticise one another – we left that to Owen and Tim, who were playing at the same time. Instead, we’d laugh, sometimes make P-Body and Atlas high-five, and leave my brain to find reasons to be paranoid on its own.

Having a friend along cancels out all the loneliness you feel in Portal 2's singleplayer. It's a deliberate part of that experience that Chell is isolated amidst the world of test chambers, but it's not always a relaxing way to spend a few hours in the way the co-operative mode can be. Once you've completed both, you're also far more likely to return to the co-op mode a second time than you are the singleplayer. Even knowing the solutions while playing with someone who is on their first run through is fun, as you get to step back and play shepherd to someone else's enjoyment.



As much as acting out the solution is kinetic and wonderful, it was the thought process I enjoyed most. Tom and I would walk in to a new challenge and think: “Um, wait, how do we do this?” We’d both stand still, playing the level through in our mind, once, twice, wait, I’ve got it! If I place a portal here – foont! – and then another here – pshoon! – then I can cover that floor with slime. Then, if I place two new portals at either end – foont! pshoon! – and now you run between them. Woosh. Woosh, woosh, wooshwooshwooshwoosh. And now I place the exit portal here – pshoon! – which will – Wheeeeeeee!

Highly Recommended: Call of Duty: Modern Warfare 3, Fifa 12.

Sit down internet. We've got a story to tell.

Once upon a time on 4Chan, a lengthy thread was started in which posters would construct an email to Gabe Newell, one word at a time. The result was complete gibberish. You can read it here. Suriprisingly, Newell apparently replied to the email with this message.

"I don't suppose it would ease your wrath if I told you we're announcing all of your favourite things at E3 2012?"

Then, a follow up message, posted on Reddit. "I can see how the wording caused some confusion there. Yes, we are announcing something with a three in it."

THREE MUSKETEERS CONFIRMED. The emails may be fake, of course, but Valve have been in a playful mood recently. There was that employee who turned up to a local game developer conference in a Half Life 3 tee. With the release of a code-filled teaser trailer over the weekend, and the appearance of the @Doug_Rattman Twitter feed, one thing is certain. Valve have started another ARG.


Item One: In which Wheatley rants against a background full of probable clues



The video above, hosted on GameTrailers, was shown as part of an awards ceremony over the weekend. In the background there are plenty of streaming numbers, barcodes and visual artefacts that are just bound to contain hidden messages.

Item The Second: In which Doug Rattman rants on the Twitters

After lying dormant for months, Doug_Rattman has burst into life with the words "It βegins."

Then he starts tweeting long series of numbers in a similar format to the ones strobing alongside Wheatley in the above trailer, things like: "AV - 10.0 | 8.2 | 12.6 | 15.2 | 7.8 | 0.2 | 17.9 | 6.9 | 21.1 | 3.7 | 21.2 | 20.4 | 10.7 - Connection Lost"

Oh god. Here we go again. Could it have something to do with an upcoming Steam sale, could it all be leading toward a Half Life 3 reveal?

Glados has escaped the confines of the Aperture Science testing facility, and has decided to spend a bit of time tormenting tower defence gamers instead. You Monster, the new expansion for Defense Grid, will add eight new maps and 35 challange missions, in which Glados will challenge you to hold back another alien invasion, noting your progress all the while and designing new tests for you to complete. The DLC is set to come out on Steam on December 7. Check out the Defense Grid site for more info.

Do you hear that faint wailing in the background? That's the sound of a thousand bank accounts going "noooo!" at the appearance of the Autumn Steam Sale. Thankfully for our wallets, it only lasts until Sunday, with dozens of new deals every day. Consider it a warm up for the monolithic Steam Christmas sale next month.

The sale kicked off yesterday, but you've still got six hours to grab some of the fantastic day one deals. The marvellous Orcs Must Die is just £2.99 / $3.74 (we gave it a score of 90 in our Orcs Must Die review). Portal 2 is selling for just £6.79 / $10.19. If you haven't played Mass Effect yet, the first game is £2.49 / $4.99, and Mass Effect 2 is 75% off at £4.99 / $12.49.

If you're more partial to an arcade explodathon starring Gordon Freeman, Renegade Ops is £4.99 / $7.49 (or you can grab a four pack for £9.99 / $14.99). All of Dejobaan's games are also on sale as well, including AaaaaAAaaaAAAaaAAAAaAAAAA!!! for the Awesome.

These games are also on sale for the next few hours:

Call of Duty: Black Ops
Duke Nukem Forever
Test Drive Unlimited 2
Risen
Sam & Max series
Men of War series
Oddworld series

 
These deals will switch out in 5 hours and 42 minutes from the time of writing. Keep an eye on the Steam front page for the next set of deals then.

Oh. Oh my. The new Portal 2 puzzle creator looks quite manageable - even for those of us who aren't sentient AIs gone genocidally mad. I mean, I'm sure we've all wanted to murder every squishy, inferior lifeform around us through a series of devious (and oftentimes hilarious) tests at some point in our lives, but it just sounded so... hard. Well, no more! Check out two new screens for proof. Also, after I've single-handedly turned the world into a series of horrific death puzzles, someone at Valve's probably getting spared for this one:

"We're also building a community site to host all of these player-created puzzles. The site will allow players to quickly find new puzzles and add them to their game, ready to play, with a single click. Players will then be able to rate the puzzles they've played, leave comments for puzzle creators, and follow creators they like."
