Good solution Lemonhead,
what about creating 50 or so CIV's for the mod; like grimorian guards, Jawas etc and give each CIV a special barracks in their city that can only produce that type of warrior. Access to a resource can be interupted, which doesn't ring true to me the wookies can no longer produce soldiers because somone choked the resource.
In this way the Wookie CIV starts with a building called something like 'jungle training pen' that did something like +1 Health, can produce Wookies.
The Sand People Civ, on the Planet Tatoine start the game with a building named something like 'Desert Bhurka' which does -1 culture, can produce sand people.
With the use of a special CIV specific barracks that civ can allways produce that unit as long as they occupy the planet. The other foreseeable advantage is that early in the game you may be able to produce enough soldiers to attack Endor and start producing your Ewoks, it would be far too hard to capture say the hutt planet, in this way as you grow in power you can dominate more and more planets and produce more and more different types of unit.
I shudder to think how much virtual memory the game would use up with 50 civs, and as i said before i'm no good with scripting, not even sure if its possible, just throwing around ideas.
CIVMANSAM, if this seems like too much research I would be happy to watch all 6 movies in the name of research for you.
What about some barbarians that travel around the space squares that are Mynocks, that slowly destroy ships?
What about some Legendary units like Han Solo or Yoda, Kaen had Legendary units in the Fall From Heavan Mod so it must be possible,
