FUDGE is a UniversalSystem for (relatively) freeform tabletop roleplaying games -- designed to support the sort of game where players don't want to spend any more time than absolutely necessary dealing with rules and tables. The "core rules" are [[http://www.fudgerpg.com/fudge.html freely available online]].

FUDGE uses custom "three-sided" UsefulNotes/{{dice}} -- really six-sided dice labeled [=[+][+][ ][ ][-][-]=] [[labelnote: note]] This can also be done with regular D6s 1-2 for [=[-]=] 3-4 for [=[ ]=] 5-6 for [=[+]=][[/labelnote]]. The core mechanic has you rate each of your character's skills on a seven-point scale, from Terrible to Superb, based on how good a result you'd expect from your character when they use that skill -- "Great Swordsman" is not just a description of a character, it's the skill that you'd put on their character sheet. When it comes time to use the skill, you roll four FUDGE dice, and move along the seven-point scale, one point upward for each [=[+]=] and one point downward for each [=[-]=]. The rules do assign numerical values to each result, and provide for numerical comparisons between results, but [=GMs=] are encouraged to just look at the name of the result and come up with some game effects to fit.

Another system that uses FUDGE-based mechanics is FATE, the core rules for ''TabletopGame/SpiritOfTheCentury'', ''TabletopGame/TheDresdenFiles'' RPG, ''TabletopGame/{{Ehdrigohr}}'', ''TabletopGame/{{Mindjammer}}'', ''ComicBook/AtomicRobo'', and ''TabletopGame/TheSmallFolk'', along with a few more indie properties, including [[http://tvtropes.org/pmwiki/pmwiki.php/FanFic/DivineBlood Divine Blood]]. Grey Ghost Press, the publisher of the original FUDGE books, sells {{Sourcebook}}s for it: [[http://derynirealms.com/ Deryni Realms]] and [[http://nagssociety.com/ Terra Incognita]]. FUDGE is the core system for Seraphim Guard's [=HeartQuest=] line of {{shoujo}}-style roleplaying games.
