Back in time then, it would have to be pretty software intensive...
but now, even my 10yo computer can (still) run a MMORPG like WoW or Roblox (!) with near instant 3d graphics. May not be l33t, but hmmm....
Imagine, a game like that, where you let your character actually live, through its stats, soul and story... with questionable choices ... crossover with the storylines of Witcher (III) universe

that would be a story in itself, right ?
