Caveman!

Billing itself as a "Prehistorically Inaccurate Wargame", Caveman! pits miniature cavemen in savage combat against one another and an assortment of dinosaurs, terror birds, and UFOs. Movement allowances are based on the players' hands (so the figures of players with larger hands move faster), and missile attacks are resolved by throwing things on the opposing player (not their figures). —user summary
