I have played with the idea of writing GURPS Utopia, a guide to campaigns set in utopian societies. Kind of the mirror image of dystopian settings like Paranoia. The big limiting factor is conflicts. Utopias don't have Man vs. Society; they normally have advanced enough ethics to minimize Man vs. Man; their people may have enough insight to minimize Man vs. Self; their technology is humane designed and avoids Man vs. Technology; and if there are gods, they're probably devoted enough to worshiping them to avoid Man vs. God, unless utopianism is a defiance of the gods. You can do Man vs. Nature, obviously, and if there are nonutopian societies you can do Society vs. Society.

Now I think of it, that's a lot like a classic "space cadet" campaign.
