Spore's first two stages were phenomenal and came the next three stages.....tribal was so quick it was pointlessly simple, world stage was ok...but once again pointlessly simple, and space just ties your hands w/ having to appease other space-faring nations and defending attacks against you that you can never really enjoy outer space exploration.
Great idea, bad planning, even worse execution. Spore = sad fail.
Cheers to you if u enjoy it tho.
