Why yes, I can. You play in one of two eras, either the Clone Wars or Galactic Civil War. The galaxy is divided into planets, and each team gets a certain amount of planets at the beginning of the game. Then, in a Risk-like way, you choose planets to invade and conquer. Once you invade, it goes into the squad based combat system. You get bonuses for holding a planet for a certain amount of time. For example, if the Empire holds Endor for quite a while, they get the Death Star.
Also, there are certain special attacks you can use (not totally sure how you get them). For example, the Empire can summon Darth Vader to slaughter everything on the screen, and the rebels can do the same with Luke Skywalker. There's like five different classes of unit you can play as. It looks pretty fun!
