@ArbitraryWater: Well I have it already installed. Might as well give it a shot. Tend to have greater tolerance for bad/mediocre games. I've read your blog again and it is no doubt it is the same as the general consensus. Still metacritic, which is of course shoddy metric has the game rated at 80%.
@ManU_Fan10ne: Thanks mate. Finished Portal 2 actually just yesterday. It is a great game, no surprise there. Didn't like the first game at all actually, but really enjoyed this one. I know what you mean for wishing it to be longer. For some of the puzzle mechanisms, like the blue wall thingie. It was barely used after the introduction.
