I posted this earlier on CivFanatics - thought I'd post it here as well.
I was fully prepared to ignore this game as an inconsequential addition to Civ, but it actually sounds fairly in depth and complex with some great features like a commodities market that goes up and down based on resource consumption, and a dynamic voting system that trumps the system currently in CIV V.
"Perhaps that's because it's being developed by Sid Meier himself. 2K says it's his baby, and you can tell. He's created a new experience that still feels like classic Civilization, with all of the strategy and depth that comes with it."
This quote makes me wonder how CIV V - or even CIV IV - would have turned out if Sid was as hands on as he seems to be with the Facebook version.
