I must say Spore has been largely overhyped in every possible aspect and people actually expected a full-scale evolution game where they'd be able to fully indulge into the process, but it has really proven to be a completely different sort of game.
Really, I had a lot of faith in this game, I expected it to be something different, unlike from all other simulation games out there, something that would let me actually step in as God and take care of every single, minor detail, but all I've seen so far is a simple, childish game with no challenge whatsoever. Don't get me wrong, it's a good game, but certainly not worth the pre-release praises the gaming community has been giving it, and certainly not the most evolutionary game in history of mankind.
Maybe if it weren't for the excessive and unnecessary hyping, I would have enjoyed the game as it is, but, unfortunately, I would still say it's just another decent simulation game out there.
Nothing more.
