I know this is not the only list, nor is it the first list, nor will it be the last list, but list, list, O list! It is my list and one more list rarely hurts any one.
Risus: The Anything RPG -
The official site itself! This site has a number of resources, mostly free, such as the Rulebook for Risus. It comes in a variety of flavors and languages!
The Risus Mailing list -
This is a solid way to keep up with what is new in the eclectic world of Risus. Though it is a Yahoo group, the Australian cliche is not applicable.
The Risus RPG Fan Forum -
Currently in a fledgeling state, so stop on by and mark your territory. This makes me want to run a Roman game inspired by A Funny Thing Happened on the Way to the Forum.
Risus TOTM -
Aka Risus Thought of the Moment, is a collection of moments pertaining to Risus gelled in amber for your perusal. The site is also code for an Irish greeting starting with a smile.
This is slowly becoming the location for Risus material. Rules and Adventures and Settings, Oh My!
Risus Monkey -
Also known as Captain Monkey in discreet regions of the interwebs, is a Stalwart Chronicler of Things Risus (6) and is a Spontaneous Geomorpher (4).
