... or, actually, I found an alternative while playing around. It turns out that at the start of the game, Boba Fett can solo the entire Empire. Obviously you don't want him fighting the fleets, but he can wipe out the entire Imperial ground force and conquer all their starting planets, all by his lonesome, by roughly Week 8.
This just confirms what we all already knew: Boba Fett is the baddest mofo in the galaxy.
EDIT: Actually, Boba Fett can take out the entire Empire
and Republic. He will do it for 3500 credits and he'll get it done in 27 weeks. What a guy.
