>>8954932A historical line might have been fun. Endless subjects and existing storyline to mess with. Could have given us samurai and mongol archers and knights and pirates and WWI soldiers and shit.
Give us small waves of 2 to 6 for each time period and call it GI Joe World Warriors or something.
Could have even tied together with some Sunbow-esque time travel nonsense and involved soldiers from Joe and Cobra's future.
