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.

Rating: 8/10

Just 8 out of 10? I must be crazy! Truth is: I enjoyed it a lot. So much, that I really wanted to have more of it, a lot more. But content was just enough for 3.7 hours in my case. Therefore it felt more like a (great) tech demo instead of a full title. Nevertheless, there is Portal 2 to continue this great puzzle journey. Get it, play it, and then continue with part 2.

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.

I have no words...

It's too solid as game, the mechanic is something that I had never seen in my life and I love it, it's the more original Valve's creations,The history is absolutely 10/10 You can't hate the main villain, in fact is now my waifu, but whatever, if you're thinking about buying this, JUST DO IT.
