FYI Kmart is having a deal on the PS3 and Xbox360 versions. If you are interested i will post the link to the sale.
I've played the original one on PC, I like the way it controls the char. I've played the demo for the second one (available on PC, PS3 and xbox). I can't get use to the controls on the console version.
I'm waiting for some reviews. I played the demo and I'm not sure I like the changes. Seems like the game was dumbed down a bit to make it easier to port to consoles, but I loved the first game.
