Noticed Doom 3 has been dropped to £5 and stated as being retina ready, used to love this game so purchased - thought it would be fun to play with maxed out settings on the rMBP. However it doesn't work. I'm shocked they can advertise a game a retina when it doesn't even work on the only retina computer apple sell! It appears to be a mountain lion compatibility issue, a friend runs it on lion without issues. Any suggestions on what to do to get a refund? I've emailed aspyr, but considering many of their titles take so long (if at all) to be patched I'm not holding my hopes up.
