I followed the game for a long time before it came out, even though I don't care for the Sims. Never actually played Spore though, heard way too many bad things.
My DVD has a scratch on it and it won't let me install it anymore
I saw that they have it on Steam as well. I was kinda hoping that I could use my CD Key to add Spore on my Steam account as well, like it's possible with many other games, but turns out not to be the case. Also EA has not yet released Spore for Mac on Steam.
