More thoughts about specs: we keep it really simple.
EMPIRE
Capital Ships: ISD, VSD, STRK, CRAK, LANCER
Starfighters: TIE/F, TIE/B, TIE/INT, TIE/A, XG-1
Auxiliary: L/SHU, S/TRAN, SKIP
Vehicles: AT-AT, AT-ST, Speeder Bike
Infantry: Fleet Trooper, Stormtrooper, ARC Trooper
REBEL
Capital Ships: MC-80, RAF, NEB, CORV, GR-75
Starfighters: A-Wing, B-Wing, X-Wing, Y-Wing, Z-95
Auxiliary: L/SHU, A/TRAN, RAT
Vehicles: T-47, Hover Tank, Speeder Bike
Infantry: Rebel Trooper, Rebel Commando, Rebel Ranger
SF/AUX/GAV Upgrades: Enhanced, Elite
Infantry Upgrades: Veteran, Elite
Now, keep in mind, this is just the spec list for all basic units. The intention is to have a Hero Unit (the Player Character) + Companion Units (less capable but still awesome) + Special Units (really beefy special purpose units, most likely for combat).
If we keep the spec list relatively small, and focus more on modifiers rather than creating new units altogether, this could make the game a bit more interesting.
