THE SYSTEM

Here’s the core of the system, including two suggested "modes." In both cases, once you've rolled, take the highest result and reference it on the table to the right.For a stat-driven game, assign a number between 1 and 3 to each stat. When that stat comes into play, roll that many d4s.In a token-based game, players can gain tokens by performing certain actions. They can expend tokens to perform special abilities, rolling as many d4s as tokens they expend.
