About This Game

Portal™ is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.

The game is designed to change the way players approach, manipulate, and surmise the possibilities in a given environment; similar to how Half-Life® 2's Gravity Gun innovated new ways to leverage an object in any given situation.

Players must solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space.

Portal is a greatly designed single player game in which you play as a test subject, and you're with this big robot thing that says the most sarcastic and some of the funniest lines ever. The game is a little bland in its story, but expanded upon in the heart warming second game. They both have some of the best puzzles I've ever seen in any puzzle game ever. Even though sometimes it can get repetetive, you know, placing blocks on a button to open something, but each level has some sort of twist to it that makes it unique and different from all the others. It all comes down to the final level and boss which test your skills to see what you have learned this entire game which is just beautifully made. Not to mention, this game came out 9 years ago, so it has withstood the test of time and has influenced may puzzle games to date. Even though it is very short it has a lot of replayability and has satisfaction to whatever you do. And anything this game got wrong, it was redeeemed in the amazing sequel, which did everything so much better than the first one. I would call this one another Valve masterpiece. 99/100

What can I say about this so famous game? Well, I guess it was amazing 10 years ago and I can see why people loved this one.

Unfortunately my expectations were maybe too high and so I was "disappointed". The game is pretty good but I was hoping for a masterpiece and as always happens with expectations I got screwed by my own unrealistic desire. Memo: Live the moment!

In fact if I think about the hours I spent playing this I can feel I actually had fun. The puzzles were not too hard, but the sense of wonder about how portals work was cool and I enjoyed that.

Too bad sometimes I had to fight the game itself (crates falling, setting portals were I wanted to, jumping). The other big issue was I got motion sickness eventually.

The last level was very cool (and way longer than I thougt) but the "boss fight" was not excpetional (again expetations vs reality).

Anyway this is a very good game, as everybody knows so I would raccomand it to anyone who doesn't NEED to kill stuff to have fun

+ Nice story
+ Very cool setting
+ Cool puzzles

- Maybe a little bit outdated
- Controls (see description)
- The portal sound effect is too loud for the music

Pre-Release Review
Posted: August 15
A great 1st person puzzle game, and a great example of how glimpses of something behind the scenes can add up to a story with desirable emotional content. (That's all I say because spoilers.) Portal's content, graphics, sounds, story, tech deserve a firm thumbs-up with both hands.

Portal is a great example of non-Euclidean geometry in a game (you enter a hole in the wall, but you don't end up on the other side of the wall, and best of all what you see behaves accordingly).

Narbacular Drop by Nuclear Monkey Software was the prototype game with user-placeable portals that lead to the creation of Portal, and (most of?) that team ended up on Valve's Portal team. That game is also worth a play.

But the first game I know of that used portal technology was Prey (2006), a *really good* 1st person shooter. Incidentally, I bought it for €1 in a German retail store a few days ago (but had played it before; those were the days when you installed a DVD without having to download anything else), so I know that it's sadly not available on Steam. With little config file editing, it runs on 1920x1080, at least that's what I set in the file, but what I saw on screen rather looked like 4K for some reason. Maybe because for arbitrary resolution, you also have to set a screen mode variable, and maybe this leads to the game using desktop resolution. I had to turn off anti-aliasing because the graphics were not fluid even though my machine can't be the reason - must be the old engine. Is fluid without AA, and I didn't miss the AA which supports the 4K assumption. Config file editing also allows to set arbitrary FoV. I played a few minutes on Windows 10 with August 2016 anniversary update on GTX980.

So, if you can get your hands on Prey today (2016), you can still play it very well, and it's still a great game. And even though it's the first non-Euclidean-geometry game I know of, it's very well done.

A very interesting little puzzle game. It really helps develop your "thinking outside the box" skills, and is wonderfully fun at the same time. I feel much smarter after playing this game, but whether I am or not, I had a blast.
