I just recently purchased the Diablo III Reaper of souls ultimate evil edition and it says that comes with a bonus Diablo 3 original game but I can't seem to find out how to play that cuz I want to start with that instead of the Reaper of souls do you think you'd be able to help me with that but I'm on ps3 if that…
