I too was sucked into SPORE.
Its not a bad game but you have to see it for exactly what it is. Those who come into it thinking its a completely custom RTS explosions and such kindof a fare will be disapointed. The game is really simplistic in nature throughout the stages of life clear up until space travel. At Cell you just eat things, which makes sense, when you come out of the water new aspects are added in but kindof stay there for the most part until you launch into space.
Once in space it becomes more of an explorer sort of game, with lots of goals and such but it all appears to me at first glance like a real deep easter-egg hunt.
I guess the real kicker for this game is the level of customization you have on your buildings/vehicles/creatures. It can get pretty complex or extremely simplistic, all up to you. But if that were the selling point for you perhaps you should've stuck to the free creature creator

Im genuinely determined to like this game, hell i bought it..
Elv if your interested in my first go at creating life the name i go by is Brownzerg
