Apologies if this is a stupid question, but this is one of those games where it seems more fun to talk about ideas than actually play.
We've talked about the various games that influenced DU, such as EVE, as well as games that it in turn influenced, such as Starbase. But what about movies, books, and other forms of sci-fi? JC frequently discussed the influence of "Ready Player One" on the game. Maybe DU could borrow more stuff from the Gene Roddenberry works for example (Star Trek, Earth: Final Conflict, Andromeda, and so on.) As for what, I don't know exactly (although I think people have already considered adding stuff from these IPs.)
