Me? I've always wanted a first-person realistic ninja game, sort of like the Thief series but you're more aggressive. You would infiltrate, kill targets, burn castles down, steal plans or blueprints, etc, all from glorious first person fashion.
Another is a good first person RPG set in feudal Japan, of course, it could always have mythical creatures or monsters in it to change things up. It would have similar game play to TES or Fallout, with skills that one could level.
If anyone posts a game idea that you think HAS been made, please point them to the game!
