Sitting here at EA Blogger's Day just got out of a session on Sim City Creator for Wii and DS. Both games are completely different. The DS version has you go through five different ages from dawn of time all the way to the future.
The Wii version is very much like the PC versions we know and love but has an accessible facade fofr new users. At its core it is very much the full Sim City experience, with all the management you want.
Off to the campus tour next.
