I don't think I've seen a lot of tribal fantasy or something similar, if there's a proper name to it. People with spears and a strong connection to the land and the gods that rule it and the air and sea and the magic they draw from them.

Disaster survival? A tunnel with a bus full of criminals and a family and a dog and an unassuming taxi driver all get trapped in a tunnel when both ends collapse and they must find a way to escape as it slowly fills with water from the river above. First come first serve. GM plays a bracelet.
