In a nutshell, DMI is an entire city where each lot was developed by a different person at GT. To my knowledge, this level of cooperation has never been reached before, and it's a pretty amazing feat. But on top of that, a complete set of custom sides has been added with a deathmatch mode, as well as a lot of other interactive things.
CW era is SP mode.
GCW era is MP mode.
