This is a reprint and expansion of one of the most popular articles from my old blog, listing some of the sites that allow you to quickly mold Risus into a number of genres and playstyles, so that whatever you feel like running on short notice is within your grasp:
It seems I've stumbled upon a lot of conversations lately where Risus has come up. I know there's folks out there who see it as either too light or too silly to do anything with. Although S. John Ross does tend to write with a fair amount of humor and whimsy, Risus is far from being either unworkable or an elitist tool. In fact, I can't think of many works written with more irreverence tempered with a combination of love and understanding of gaming. Some games attempt to be a psychiatric session; others push too hard to be a One True Way. In my mind, Risus still stands for Beer n' Pretzels. It's rules-light, sure, but it's friendly, fun, and accessible to most gamers. I think that's something we can all admire.
Just so you don't think Risus is for one-shots and tongue-in-cheek play only, here's a look at just a few of the genres people have undertaken using Risus:
Supers: Risus Supers
SciFi/Space: Travelling Light (My personal favorite)
Horror/Conspiracy: Cthulhu Risus
War: Risus Tenhut
Wild West: Risus Wild WestYou can find tons more at Risus' fan sites page. Have fun!
