I'm kind of worried about Spore.
There's the standard "it won't live up to the hype" complaint, but few games do, and even if it doesn't it'll probably be pretty awesome. I've enjoyed every other Will Wright/Maxis game I've ever played, so I'm not worried about it not being fun.
What bugs me is -- IGN describes it as an "evolution game." It's not. If anything, it's an intelligent design game. Which doesn't bother me, intrinsically, because it makes a much better, or at least more approachable, foundation for a game.
But I do worry that describing it as an "evolution game" will get people mixed up, or that it's a sign that they're already mixed up. A minor worry, but something I think about.
