I'm glad it is possible though and hope you enjoy it. I'm busy trying to clear the backlog of Windows stuff I have so I can delete my bootcamp partition. Speaking of backlogs, I probably still won't be caught up by the time perhaps Feral or Aspyr ports it anyway, if they do.
I haven't played CoD since MW:3 campaign that was enough to tell me I had out grown the series. Not dissing COD as COD:4 still has a huge Mac player base on Game Ranger.
