None of the main characters of the show exist (except Cagalli and Lacus and certain political figures), so it'd be an alternate timeline that can go any direction. A wide range of character concepts would be available such as pilots and captains (obviously), but also politicians and generals for swaying the direction of their power group and spies.

It would also be PvP where players have to choose ZAFT or the Earth Alliance. Orb Union is an option down the line if the game were to be popular enough.

System?
