Risus is a nice simple little RPG that I think everyone should probably play at least once. I personally don't feel it fits my playstyle because of how freeform it is. It also tends toward comedy, in my experience. I don't know if I could sustain a long-term campaign Risus, but it's definitely great for a fun oneshot. RPGs are stripped down to their core here, so if you dig that, definitely check this out. Screw playing D&D in the office, play this instead!
