Next, they'll add AI fauna and an intelligent race much like our own. They'll jack the speed up to high and use it to see how problems in our own future might arise and be dealt with.
Every so often the administration may have to make some sort of "god" type AI to pop in and try to keep things heading on track in the directions we need it to go. I can't wait till they get up to traveling to their moon and seeing if they decide to fake it, or go at it for real. Hopefully we'll be able to keep the simulation going long enough without it destroying itself to see if they can solve interstellar travel in a way we can copy. Otherwise it'll need reset so we can try again.
