The Lusty Argonian Maid... er probably one which had representations of loved ones lost. I may not be able to program their personalities, but to even see 'them' again with my own eyes would be beyond words.
Weapons, weapons, and more weapons! It's hard to imagine many things more fun than being able to go nuts with every sort of weapon that ever existed without any care for collateral damage, from 21st century rifles and rockets, up to phasers set on full and see how much they truly can disintegrate in a virtual environment! Plus every imaginable combat scenario to train in self defense.
yeah there would be some naked women involved, but other than that id probably run sc-fi programs (like being on the bridge while fending off a borg attack) or fantasy adventures. like lord of the rings or something.
