First of all it depends on your system. But why are you posting in here about getting your money back?
Shouldnt you be taking that up with battlefront? Most people in here love the game including myself, and you can just imagine the type of response your gonna get from this thread. It does say "All Sales are Final" when you order, That must be a hint...
That being said, If you dont like the game. Sell it, throw it away, do whatever you please with it. Dont take up space on the forums about bla bla bla having your money back and stuff. Cause then all of us have to sift through this BS to find threads we all can discuss about the game.
