PAT: Friends and Buffaloes

User summary: The game is for five players and one game master. Players in the game control characters who are farmers. The characters must graze their buffalo stock. Farmers have individual goals (generally, to maximize their buffalo herd) and collective goals (to preserve the grasslands) - these goals are fundamentally opposed. The game is played on a grid surface that represents grazing resources. Resources regenerate naturally, but more slowly than they typically are consumed. To simulate pine tree encroachment, the game master removes usable grids from the game at regular intervals.
