I have already talked about this matter I think but considering how close the release might me I thought I would delve deeper into details. As mountain lion shall have game center I have some expectations what firaxes might do. First of all if you buy civililization 5 on the Mac app stores I think that it will interact with game center. Second also what I think is that civ rev will be playable and downloadable on the Mac apps store. Also I think that now with iCloud you can play civ rev on your iPad and continou on you Mac.
