I have been thinking of getting a tablet and wanted to play Civ 4 on it. I own the PC versions of the game but would be willing to purchase the MAC version. Problem is, is it possible to install Civ 4 on an iPad, for example? Would the up-coming Windows 8 tablets (with an Intel chip) be a better choice? Note that I do not want to remote to my desktop, I want to be able to physically install Civ to the tablet so I can play it anywhere. Thanks.
