Civilization Beyond Earth has been released for Mac just a couple days ago, you can buy it from the App store and Steam. Firaxes and 2K have also announced that the Linux version of the game will come soon.
I will now install Civ BE and just play around with it and write a post about my experiences later.
Civilization Beyond Earth was just released yesterday on Steam and on CD Rom for Mac, PC and Linux. I expect it to be released on the App store most likely later this year and hopefully come with Game Centre Multiplayer support.
The game costs now 49.99 Dollars but if you want to save a bit of money I suggest you wait till the winter when the game will be more stable and Steam most likely put a discount on it.
But if you can wait and really want the best and the newest games out there or you are a avid civ fanatic and need to buy it now, the reviews have been very good and price is fairly reasonable already.
The release date of Civilization Beyond earth has been announced. It will be released worldwide on the 24th of October. It will be released simultaneously for PC Mac and Linux (unlike with Civ 5 where it came a whole two month later out). Although availability has not yet been clarified it will most likely have a CD download including a digital download from steam. It is not clear if it will be released on the Mac App Store on day one.
So it seems first of all that beyond earth (the new civ game) will be official released somewhere in september, a clear date has not been given yet but judging by the last release dat of 10 September or Civ 5 it will probably be released again early in September.
Then most likely it will be released a bit later for Mac most likely a month later. For OSX the likelihood that it will include snow leopard in the system requirements will in my opinion be quite low.
For Windows it is hard to say but I think that Vista will also be dropped for the new Civ Beyond Earth game.
So in the end my prediction with using facts is:
Windows Release: September 10th System Requirements Windows 7 and higher
OSX Release: October 22nd System Requirements OSX 10.7 and higher
