In the end, Spore delivers exactly what it set out to do. Due to its very nature, there will be some people who are not completely happy with the game. Perhaps something they liked didn't get enough attention or something wasn't fleshed out as much as they would have wished. When you get down to it, people are all like that as gamers. They get caught up in the hype and they forget how massive a game would have to be to encompass the very best of everything we imagine a title should be.
Spore successfully redefines what it is to be a civilization game, not because it's the best one of the category, but because it successfully bridges the gap into other genres and brings them into one, cartoony, fun addictive game that is a hybrid of everything.
