Being spread out can be advantagous. Sending even 1 construction yard to places across the galaxy, and in a couple hundred turns, u have the entire sector under your control. Send out any medium transports out, to servey system by system. if u find planets that have large capasity, land a troop regiment, then send a couple construction yards over. To gain a foot hold, send out diplomats. good idea is to concentrate them in one sector, if u want it raelly badly. i like to fan out. have mon monthma, luke and leia recruiting. the empire usually has a great many planets that support u, but are garrisoned. to take em over, use my last suggstion about sabatures. Hand and chewie can be very usefull...
