Currently i am also playing Star Wars: Commander (german site) where you can decide whether to fight for the Rebells or the Imperium. Build up and improve your base as well as troops. Fight other players in guilds or alone or fight the NPC. It has a story to play to make some progress.
If anyone plays it let me know. If we are enough we could think to make an SWAT guild and fight others ;)+
