Mark Dain GTA 5 doesn't even launch on my PC (I get "disk write error"). Does anyone know if I can get my money back on Steam?

😀 Tom According to their terms and conditions, yes. They should also be able to tell how many hours you spent playing the game, and since it's zero, they should give you the refund. Keep in mind that with Steam, 9 times out of 10, "should" means they still won't.
