Brilliant game. Just got it yesterday and have been loving every second of it. [video=youtube;wX9Sc88qreg]http://www.youtube.com/watch?v=wX9Sc88qreg[/video]
It's supposed to be about a 10-12 hour game from what I've read, which isn't bad. I'm thinking of picking it up. I've been on a game buying binge recently though - in the last month and a half I've bought a 3DS, Pokemon White, Ridge Racer 3D, Dead Space 2, Crysis 2, WWE All Stars, Mortal Kombat, Bayonetta and Bulletstorm - so to say the least, I have a shit load of things to play and I'm not sure if I can justify the purchase of another game at this point in time.
Last game I got was NBA 2k11 which I bought myself for Christmas. Haven't touched it in a few months though. Still, probably shouldn't buy anything until the summer. I'm too good at procrastinating as it is, don't need another tool to support my laziness.
And I caved and bought it. It's actually installing to my 360 as I type this. And I wish I could prevent myself from buying games, but if I have the money, I don't care. I've bought a ton of games recently, and there's at least two more that I'll be getting in the month of May with Brink and L.A. Noire coming out in consecutive weeks, as well as DOA Dimensions coming out on the 3DS. After that I have The Legend of Zelda: Ocarina of Time 3D in June, and god knows what after that.
Don't worry, it's not. It's actually way longer than the first. It's suppose to take you twice as long to finish than the first game... Or more. And of course it also depends on how fast you can finish the puzzles themselves. I've put about at least 4-6 hours into it and I'm sure I'm like halfway through the game.
I've read it's about a 10-12 hour game for the main campaign, and then there's also the co-op campaign (which I haven't heard anything regarding length for that)...as opposed to the first game was maybe a 3 hour game.
The first Portal wasn't a full game, Portal 2 is. So it should be a hell of a lot longer than the original. I'm defo picking this up, but i'm going to wait till i move back to uni.
