No downtown, colleges, exotics in The Sims 2 ultimate collection.

When you got into the neighborhood overview (with the buttons at the top,) did you see a "+" on any of the icons? Downtown and places like that aren't there from the start, you have to add them by clicking on that button. It should have a "+" on it.  If you are having a different problem, please tell me if the buttons are greyed out, or not there. What I just said was: you have to add them first, with the buttons that say "add a (district)."
