Fata Deum cites Black & White and Populous as inspirations, and it sure does look like a god game in the classic mold. You get to lord it over a bunch of tiny people, granting their wishes with miracles or punishing them arbitrarily at your whim. If God really is a gamer, we're probably screwed, aren't we?
One of Fata Deum's hooks is that it's got a day/night cycle and, while you can spend the days doing miracles, building up your civilization, and striving against rival gods, at night everything gets more chill. You spend the hours of darkness planning long-term strategy—and also whispering into people's dreams.
