I've had my eye on this for a long time, because it looks like a rare innovation in the city builder genre. You build a village on the back of a giant beast (Onbu). Instead of a summer / winter cycle, the "seasons" are actually different biomes that the beast walks through, which will all have effects on the environment. There's a research tree where it looks like you can either care for, or exploit Onbu - like mining it for resources or feeding it. Onbu walks through a beautiful 3D world, but your buildings and citizens are completely 2D, which works pretty well. The UI is nice, and there's a cool mechanic where you can see the road Onbu is walking down, and events that are going to happen.
