There should an Aviation MMORPG where the entire world was modeled to say, tenth the size. Players would start out training in small Piper Cub with a licensed pilot until they themselves qualified for a Pilot license. Then they would move on to the larger aircraft if they choose, perhaps twin piston aircraft. It would be a period game, let say set in the 1940's (expansions would be proceeding decades). The classes could be private pilot, for those who like to fly around and see the sights from afar, commercial pilot that would pick up NPC’s at terminals and fly them around for franks and the such.
I can't wait for a real eugenics movement, i'm bored by short people.
