Heya. Just popped in and noticed that Risus isn't on the list. It's a cute little free gem that's based entirely around rules-light principles. Basically, you create your character on a single index card based on certain clichés (from the rules examples given, things like biker, spy, nerd, supermodel, or Shatner), ranked roughly based on skill level up to ten dice total. It's pure d6 for combat resolution (where combat is any opposed action, like fights, arguments, or duel by banjo), where you can use whatever cliché you can justify (even completely inappropriate ones like fighting a barbarian with your home ec skills, as long as your description is entertaining enough). Website is here, and it's a free six-pager. It's worth taking a look at, certainly.
