The original Civ Rev was released in 2007 and 2008 on the app store and now I am wondering if there is a future for the game. And you might be quite surprised because I think there is a future for the Civ Rev iOS version as I think it is the only one that has the potential as the mobile gaming community including iOS is community is growing much faster than the other platforms like XBOX . Also as mobile hardware starts to becomes more powerful Civ rev will get better graphics or cut scenes.
And if you are a Civ rev user you might have already seen that Firaxes paying more attention to there iOS version like game center integration. It is also one of the few games that support iCloud. So if Civ Rev iOS is getting updates quite frequently (even more than civ5) what could we expect!
Also there might be a chance that they could decide to make Civ rev a sub franchise. But still is very unlikely to happen :).
