Two points:
1. There will be a sandbox mode that is not counted on the leader boards nor shared with others so perhaps a trainer could be used in that fashion. Honor system is all you can really say on that point.
2. Calling it SimCity for Dummies is not the correct view in my perspective, I would say it's more compacted than anything. I will miss the large cities from the past though.
I would agree that it is compacted for the masses instead of being geared for those us of who have been playing since 1989 and enjoy the challenges of those past games.
I will also miss the massive all-in-one cities of past Sim-Cities.
