Hollywood studios have approached Valve in the past to explore the possibility of adapting Half-Life for the silver screen, but before you could spit out "Uwe Boll," Valve declared that any sort of movie involving Freeman and Friends® would be created by its very hands. What-ifs persist, of course, and in an interview with New Rising Media (via VG247), Half-Life writer Marc Laidlaw named Hellboy and Pan's Labyrinth director Guillermo del Toro as a good fit for a hypothetical adaptation.

"Guillermo del Toro has the horror vibe that I think a lot of people miss out on when thinking about a Half-Life movie," Laidlaw said. "Half-Life is essentially horror after all. The science in it barely passes as hand-waving, but when a headcrab jumps at your head, it’s a precisely engineered jolt."

Laidlaw also thinks Total Recall and Starship Troopers director Paul Verhoeven could concoct something "insane" for a Half-Life film, and pointed to The Lord of the Rings' Peter Jackson as a "purveyor of faithful adaptations." "There are probably a lot of good potential directors, but I think most of them are busy pursuing their own visions," he added.

Regardless of who would come aboard for the supposed project, they'd need the thumbs-up from Valve boss Gabe Newell, who holds a rather soured opinion of what Hollywood offered him so far. "Directors down there wanted to make a Half-Life movie and stuff, so they’d bring in a writer or some talent agency would bring in writers, and they would pitch us on their story," he told us. "And their stories were just so bad. I mean, brutally, the worst. Not understanding what made the game a good game, or what made the property an interesting thing for people to be a fan of."

Hotline Miami is all about learning through repetition, then executing a perfect murder ballet.

Tyler Wilde, Associate EditorThe word "repetitive" commonly has a negative connotation, and it's especially used negatively (all the time, every time, forever and ever) when talking about games. And often it's followed by a bunch of no elaboration at all. That doesn't make sense. I'm sure I've done it before, but criticizing a game for being "too repetitive" and leaving it at that is—strictly speaking—meaningless. A game might lack variety, but every game is repetitive. We repeat some pattern of input—running and shooting, stacking blocks, bouncing balls off blue dots—over and over, and expect uniform feedback. Then the problem changes slightly, and we tweak our input pattern. And then again. And yet "too repetitive" is lobbed at games all the time.

Alright, I know that sounds a bit pedantic, and I do recognize the difference in tone between "repetition" and "repetitive." Lack of variety is a fair criticism, but "too repetitive" is an extremely vague way to say it, and it dodges the truth: when we criticize a game for being "too repetitive," I think we often mean that we just don't like what we're doing. "It's repetitive" is shorthand for "this isn't fun (for some reason)."

If we like what we're doing, repetition is desirable. I like solving puzzles in Portal, and once I solve one I want to solve more. I don't want to solve the exact same puzzle again, but I don't want to stumble into a surprise Sudoku chamber, either. So Portal gives me increasingly clever arrangements of portal-ey logic problems. The puzzles get harder, but they're all just iterations of the same basic spatial problem I solved in the first puzzle. So after all my twisty, knotty figuring arrives at a solution, it always seems just as simple as the first time. That sense of clarity comes from repetition.

Super Meat Boy replays your failures, illustrating your own learning process.

Repetition is also how we learn, and both Super Meat Boy and Hotline Miami succeed by embracing that power. They present problems in small chunks—a level in Super Meat Boy and a floor of thugs in Hotline Miami—and rapidly reset them every time we fail. Each attempt gives us new information to apply to the next, building layers of experience on the way to that one perfect run. And that perfect run feels good: it's an accomplishment, like unknotting an especially tricky puzzle in Portal. Except in Hotline Miami there's more brain-stuff and skull chunks lying around afterward.

The same goes for Counter-Strike, StarCraft, and the rest. At their most basic levels, they're about repeating and mutating input patterns to solve variable, but not totally unpredictable, problems. The variables in Counter-Strike, for example, are the guns, maps, and opponents. That's been enough variety to keep us repetitively shooting at each other for 13 years.

Repetition can be pretty damn fun, so we've got to be specific, and always ask ourselves if it's really the repetition of a theme that bothers us, or the theme itself. I can shoot bad guys all day, so complaining that "the shooting is repetitive" in Medal of Honor: Warfighter would be confusing. Further examination would reveal that the guns, maps, and enemies have specific traits I don't like, which has nothing to do with repetition (except that the more I do them, the less I like them).

Fearing the dreaded "repetitiveness" may even be bad for games: that's probably how we end up with off-key phrases at pivotal moments, like a boss fight which takes away the gun I've been using the whole time and sticks me in a surprise platformer. It's variety, but it screws up the whole composition. A performance of Rachmaninov's Piano Concerto No. 2, for example, would not benefit from an unexpected dubstep interlude. No, I wasn't talking to you, Skrillex. Are you drunk? Go home, dude.

Anyway, if at first glance this looks like an ostentatious rant about a personal pet-peeve, then you may have seen correctly. But maybe not: try Googling any game name with the phrase "too repetitive." It's everywhere. I get what's meant by it (sort of, kind of, some of the time), but it says very little. It may not even be a criticism, because games like Hotline Miami wouldn't be fun without repetition. If dying and respawning didn't reset the level, and our prior kills stayed bloodied, it would be ruined. Maybe then we'd say that it's not repetitive enough?

Nailing down the range of possibilities afforded by modding's creativity yawns past the comprehension of us mere mortals. Yet, for a platform housing exploding horses, rug-cutting Combine, and the nesting-doll appeal of Minecraft's game-in-a-game sandbox, the PC keeps its lot of closed environments precipitated by developers and publishers as a means for balanced gameplay or brand protection. In an interview with True PC Gaming, Black Mesa Project Lead Carlos Montero flatly stated such a hindrance for mod growth "doesn't make sense."

"When you think about it, modders are like the ultimate fans," Montero explained. "They love this game so much, they're doing real, difficult, skilled work that you usually pay people for. Not only that, but they can add so much value to your game for the rest of your audience. Yet you still see companies look at this as competition. They sue and shut down these projects and ignore or drop support for people to mod their games. It doesn't make any sense. In my opinion, it’s the product of businesses (or lawyers) looking at this too analytically and short-term without understanding the long-term value it can create for their games."

Although Black Mesa earned the silent blessing of Valve during its lengthy session in the testing chamber, other ambitious projects met a not-so-friendly response from license holders legally stifling efforts. Montero's thoughts—the rest of which you can read in the interview—reflect a sentiment by modder-turned-developer Tripwire Interactive expressing confusion over why companies would stop mods on their games.

For Valve's employees, working at one of the most secretive development studios around constitutes a once-in-a-respawn experience. The leakage of Valve's employee handbook earlier this year colorfully outlined a flat management structure culturing a counterintuitive emphasis on peer-driven independence. Speaking to Seattle Interactive Conference attendees yesterday (as reported by GeekWire), Valve Product Designer Greg Coomer said the same free-form philosophy governing the company's work ethic also factors into firing someone.

"I wish that we had covered firing in the employee handbook," Coomer said. "It was one of the things that we left out. We tried writing it, but we didn't feel like we were capturing how Valve thinks about (firing) in a well enough way. It was almost a wording problem. We couldn't get it done in the time that we wouldn't to finish the handbook. The short answer of how we handle terminations, really, is the same as we approach all other decisions at the company: It's a peer-driven process.

"If it turns out that we made a bad hiring decision, or that somebody is just not working out, there’s a method we use to get the people who are involved in the same room and to walk through the decision about what should really happen as a result of this person not functioning very well. Some of the details are kind of boring, but the main answer is that it's peer-driven, just like we evaluate each other as peers.”

I wonder what a caricaturized "Termination and You" chapter in the handbook would look like—probably the Pyro immolating an office chair or something. Still, Coomer attributed Valve's higher rate of self-fulfillment to the significant flexibility it bestows upon its workers, saying, “There are attributes that other companies have quoted about themselves that they allow their (employees) to spend some fraction of their time actually deciding on their own what to work on, but at Valve that percentage of your time is 100 percent. Every single person is responsible for deciding what they do every day."

Of all the user-made interpretations of Half-Life's doomed resonance cascade in the Black Mesa facility, the version fashioned by Minecraft modder "Xannot" might very well include the first Swiss-cheese-lined test chamber. Really, Xannot's Minecraft-ed Black Mesa appears quite faithful to the original, with explorable hallways, tram rails, and an open-oven microwave.

The mod's forum thread details the ongoing scope of completion (up to the first Houndeye encounter so far) and a handy download link for interested miners. Hopefully, Xannoc will add subsequent portions of Gordon Freeman's journey, as his efforts already look just as ambitious as other noteworthy creations.

Since its launch, Valve's Source Filmmaker has helped budding directors create literally hundreds of movies - some good, some bad, most.... incredibly goofy. The Team Fortress 2 cast especially has sung seemingly every song, played out every meme and worn every hat and every expression - sometimes at once! But what are the ten best creations? We've scoured YouTube in search of the funniest, the most dramatic, and the just plain prettiest Source Filmmaker movies.

Scout vs. Witch



Easily one of the best directed SFM movies out there, mixing Team Fortress, Left 4 Dead and a fine sense of timing. Scout (no relation to Scout) is one of the more popular TF2 mercs, with his cockiness the perfect antidote to all that zombie misery. At least, while the moment lasts.

Just One More Hat



And he's back, in this fashion-conscious spin on one of Disney's most parodied songs. More worksafe than Dirty Little Mermaid, more morally conscious than Slaughter Your World, it also wins bonus points for having an original TF2 version of a song instead of just looping in a more general one.

Meet The Family



Mostly made (naughty naughty) with the leaked SFM, this was one of the first epic projects to be finished and still one of the best. Scout and Spy team up as literal brothers in blood to kick off a perfectly choreographed race for that all-important Intelligence. Guest starring music from The Incredibles to add pace and more than a little style. No "da-da-da" sting at the end though.

Adventures Of The F2P Engineer



He's smart enough to whip up teleporters and sentries on the battlefield... but he didn't pay for the privilege, so he's probably doing it with his flies open and his shoes undone. When he's having this much fun though, can you really begrudge him? The answer is yes. Even if you're on the other team, sometimes it just gets... sad. Luckily, there are other engineers on hand, like...

Practical Problems



An epic war between two professionals who know what they're doing, but don't know when to quit. A little parable about the importance of good manners, respect, and most importantly, not ****ing with another man's sandvich. A true Lesson For The Ages, with some fine music right alongside.



Meet The Soldier (Directed By Michael Bay)



We're firmly back in parody territory for this one; a relatively straight replay of Meet The Soldier, but with rather more boom and a surprising (though not unwelcome) lack of Alyx, Zoey, Rochelle or Chell forcibly being draped over a motorbike or anything at any point to complete the picture of one of cinema's most successful nostalgia murderers. Love or hate it, it's better than Transformers 2 any day.

The First Wave



It's not just a game mode... it's war! Mann vs. Machine gets dramatic in this epic four minutes of the mercs facing their durable doubles for the first time. Bonus points for a return of the disembodied Blue Spy, and a death scene with the power to spawn a thousand bits of erotic TF2 fan-fiction. Which exist. You'd better believe they exist. You have been warned.

DOTA Hero Pals: The Mysterious Ticking Noise



Not so much a 'parody' of the Potter Puppet Pals original as a straight copy with DOTA characters in it, this is still one of the more accomplished movies to come from that game. We just need another eighty or so instalments to cover the other characters, and I see no reason new players shouldn't have enough data to compete at professional level/troll like champions.

Heavy Doo, Where Are You?



I never understood "Scooby Doo, Where Are You?" as a show title. Admittedly my memory is a little fuzzy about the actual cartoons, but I definitely remember Fred, Daphne and Velma doing most of the mystery-solving gruntwork, with Scooby's role being to blunder into helpful things. If you called him, you'd prevent him from doing that. The song makes no sense, is what I'm saying. This movie is more reasonable. If you had to fight Old Man Peterson, having a Gatling wielding Russian psychopath on hand definitely beats anything Scrappy Doo could serve up. Admittedly, so would a crouton.

After Aperture



Chell's life after Aperture isn't exactly unexplored territory, but this Exile Vilify backed slice is one of the more interestingly melancholic SFM movies so far. A little clunky in terms of animation, largely due to the poor Chell rig (at least one other movie opted to reskin Zoey instead of using it), but it makes up for it with a different kind of atmosphere to most and that lovely outdoor setting.

Those are our picks, but there are many more SFM movies out there. Have any particularly caught your attention, impressed you, or just made you laugh? Share their names below...
