You can find some new information – and old information on Spore in the following article by heading to The Tyee.
“I’ve been lucky to have enough successes that EA [Electronics Arts] doesn’t seem to care how crazy my idea is. They’ll back it. I told the executive team, “I have this great game, powers of 10, custom content, da-da-da-da….” They didn’t know what I was talking about. They just said, ‘Go do it.’
“The challenge has been with my team. With Spore, I brought 10 core team members in and told them what we were going to do. It went across genres, custom content for every level, procedural animation…. It sounded like too much. They looked at me like I was crazy. For me, that was the pitch job — convincing the team that we could build it. They played devil’s advocate, had a lot of great feedback, and we directed the design away from the areas they thought were land mines.”
