It's basically Sim-god. You play a floating hand that can move people around and do a few other miracles and such. You rule over a tiny village and can have enemy villages you must convert or destroy the villagers of. Their gods try and do the same to you. Your actual power is limited and a lot of stuff can only be done through your pet who is a giant monker, cow, lion, whatever else they have. It's a pretty nifty game, worth $20, but after a few weeks of the origional I never touched it again. If it had multiplayer in the origional, it was really weak, but I think it just didn't have it. Which was a big part of why I stopped playing. Single player strategy games are just dull. Either too easy or absurdly favoring the computer (Ie 500 zergling rush 2.3minutes into a game when playing sacrifice map of Starcraft vs all 5 comps.)
Judging from description they added a lot of Strategy wargame elements to it now. It'll either make it a lot more interesting or else make it so damn micromanaged (the origional required HUGE amounts of micromanagement to accomplish anything) it's impossible to play.
