Question 1: have you thought about calling the unaligned forces Black Sun? (if they represent the underworld)...
Or it'd be great if you could make a pirate faction called Black Sun with StarViper ships and other infamous underworld vessels. That's one thing I hated about Empire at War was that Zann's faction should have just been the Black Sun. Xizor was really the head of the Underworld, and if not him, the Hutts. Maybe they were trying to be original.
Which leads me to...
Question 2: could you incorporate "leaders" into the mod? May sound strange, but just hear me out...
For example, factions can build certain ships (obviously we can't have a physical person in the mod) that are already high in rank flagships, like:
Alliance: Millenium Falcon (Han Solo), Rogue Squadron (Luke Skywalker), etc.
Empire: Death Star (Grand Moff Tarkin), Eclipse (Palpatine), TIE Advanced (Vader)
Black Sun (unaligned forces or Pirates): Virago (Xizor), Slave I (Boba Fett))
Don't tell me to go play EaW or whatever, haha, I just think that this might add a different element to the gameplay. Man, I wish the vanilla races had leaders even... hmmm...
P.S. Sweet Mod.
