Need help buying games for iMac
I need some help on where the best place to buy games for my iMac - I am looking at purchasing Sid Meier's Civilization 4 or 5. I have been going through the OZB forums and I see alot of mention about cheap games from Steam and Amazon.com. Can someone please explain what the difference between buying from the two? I am aware of Amazon.com needing a US address to be able to download the games so I need to use some US address generator website to get around that. I am only interested in download versions of the game.
Thanks in advance guys!
