I play the CIS everynow and then. But my favorite has to me the Empire. I don't think the rebels are very strong unless your the Regular Infantry. I like big armies...and the Clones and the Empire have the biggest.
Well of course their the same. But anyway i play the Droids when i feel like losing or when I play a non-playerselect and i have to.
p.s. I think its just im not good with them...
