All Combinations (36) of Six Geometric Figures: The RPG.
This concept recasts geometric figures as RPG characters. There are heavy-hitting characters and mages and summoners and healers and whatever else, separated by shape. Their shapes tell you what they do.
With your party of three shape-characters, you face off with other teams of three in a long series of turn-based battles. The game is over when you’ve beaten every team.
