How creative can we be? One of the great things about Evangelion was how it turned from sci-fi to almost spiritual fiction (at least how I saw it), so there would obviously be a lot of hidden aspects of our characters to develop later on... That being said, are they "just" Eva pilots? Can we have funky-yet-plausible prototypes? Can we go deep in our backgrounds and set up stuff for later on? I guess it depends how linear you want to go with the series' storyline.

Yes they don't even have to be eva pilots if you want they could be a important person at Nerv or what have you, and yeah you could have prototypes as long as you run them by me first I don't want things getting too crazy. This will drift from canon slightly so as to make a functional game.
