Portal 2 (PC & Mac)

Personally I thought this game was much longer, and a bit harder that Portal 1, I played it intensely 3 times and completed it, but otherwise played normally I think it would take a while longer.

Would definitely help to have completed Portal 1 story and skills wise, but even if you haven't the main story line could be easily picked up, maybe just wouldn't understand various 'in' jokes ;)

I thought it was excellent, I had high expectations from Valve as I throroughly enjoyed the first game, but they definitely succeeded in my opinion. It's very funny and even a little bit scarey at times due to just being alone in this humongous testing facility. Stephen Merchant's character Wheatley is hilarious and it all works really well.

Highly recommended, well done Valve!

Ok the game is short, for me i spent about 12 hours for both co-op and single campaign's however they were a great and memorable 12 hours.

some people have said that its too short for a full priced game but most games are not great from start to finish (Portal 2 is) they tend to get repatative or spaced out and time consuming between getting to the good stuff.

But there are some great puzzle mechanics in place and when the SDK comes out it will be great to see what mods and maps the community will come up with.

Fantastic game. The game uses the old source engine however, there are a lot of tweaks, Graphics are much crisper and the detail in general is better. The game seems to just go on and on and on! Took me a good few days to complete (Only on for about 2hours each of the days). Co-op is fantastic, having to help one another through the courses etc. All around awesome game and a massive improvement on the original. Great laugh, highly recommended.

I loved this game from start to finish. From Stephen Merchant as the supremely funny [unintentionally] Wheatley, to J.K. Simmons as CEO of Aperture Science, Cave Johnson; the game was a blast.

The humor in it is top notch, with GLaDOS being just as callous and spiteful as ever, and the puzzles in it incorporate new features like hover lifts and refraction cubes. I've played single player for 9 hours, which it took me to complete it. I found it thoroughly enjoyable and the new, updated source engine is a marvel to see how everything moves and evolves as you go through the chambers.

I would fully recommend this title to any fans of Portal, and even those who didn't like the first one. The advances in the game over the first one are almost unbelievable in how far they've come. There is a fully emerging storyline [unlike the subtle, down-played storyline driving the first game] and it really draws you in.

Buy it and enjoy it. Valve have created another cultural smash hit.

Single player mode
At a beginning it was impressive and after 10 minutes of game play it started to annoy. Unsatisfied I already started to count things that dislike (example: faulty core's (with blue eye) voice was like real human's - without any distortion, challenges of the levels seamed very easy and the story line the same as in portal part one), but at the other part of a game everything changed - I started to like it more and more and then I finished last stage... ... I am gladly putting this game to other valve masterpieces.

For two players game mode - no complains :)

Amazing computer graphics.
Runs fluently (no crashes experienced).
Storyline and some characters could be a little better.

Verdict - really worth buying and playing.
