Fast, simple and fun. These four pages contain a surprisingly deep system. In some expensive, high-quality RPGs there are different systems for hand-to-hand combat, car chases and rap battles but in Risus - it's one mechanic. The presented rules for character advancement would not work for longer campaigns - characters would become too powerful too quickly. If you intend to run a campaign in this... well, I will certainly try. But it WILL require some extra tinkering.
