A suggestion regarding music/sound effects:
Unless you want a cease and desist from Bandai Namco you obviously can't include sound assets ripped from the AC series, but that isn't going to stop me from modding them in myself.
It'd be convenient if Project Wingman included a nice drag and drop way to replace the default sound assets with something custom...
