This is the type of game I would normally like. And I've been interested given all the buzz it has generated. I tried the creature creator but it was only fun for a few minutes.
I'll probably get the game but I'm not sure that I'll play it much, I like an open ended simulation the most and this one sounds like it has stages and a timeline, even though proceeding through it is supposed to be pretty open.
I don't play many games, so it's going to have to be a very good to get me to game a bit.
