That would be a good idea, except you'd need a good internet connection, and I don't see and activities people in US could do.
HOWEVER....., if soneone creates a game I have an idea for (hint,hint), which is like an earth simulator where you do everything from create the earth to customize the genetic structure of different genes. There could be expansion packs, of course, to put in the more advanced features, but it would be awesome if this could connect to universe sandbox (hint, hint).
