A harem of young, busty, blonde and light-brown-haired Polish and Lithuanian women who never age for all eternity and whose boobs are perpetually perky and libidos perpetually set to overdrive.
A section of Heaven set aside for every Capitalism, Europa Universalis/Victoria/Hearts of Iron player who plays semi-cooperative multiplayer (keeping alliances in EU/Vic/HoI, creating mutual manufacturing/business chains in Capitalism), for every Simutrans/Transport Tycoon player, where the LAN parties are always on and the new pak128 mods, chains, and objects in Simutrans flow from the hands of the gods by the very thoughts of the players...and a whole Hanseatic League's worth of Patrician III players in a multiplayer match that would have the feel of an MMO.
As a diversion I'd get my own world to be god of and I could control it with the ease and total authority of a Sims game...including the sometimes unexpectedly hilarious actions from the little people.
