It's amazing what they did with Spore. From what it sounds like, the original Spore release was EA selling the foundation of a game, only that it allowed the players to put in the pieces. After the pieces have been created, now various games can be put on top of it. It's almost like EA has leveraged the game playing community to build a free MMO for them. I'd probably play Spore if I wasn't enraptured with Fallout 3 (140 hours & counting).
