The official civilization5.com site is reporting that if you bought Civilization V off of Steam, it will support SteamPlay. What does that mean exactly? Well if you bought the Windows version, you will not have to rebuy it to play it on your Mac. I was one of those people that picked it up on launch and had to use Boot Camp to play it off of my computer, well those days are now over! Now when does it release for the Mac? Today! So jump on it, it is really a great game for any strategy gamer.
