#ArsMagica #ttrpg, famed for it's flexible magic system and troupe-style play, has launched their definitive edition crowd funding on #backerkit. Although the overall system is a bit clunky, the magic rules for casting freeform spells are great, and I try to play the game at conventions, etc, whenever I get a chance.

And, as part of their stretch goals (which they have already reached a bunch), they are releasing the game text under #OpenSource #CreativeCommons licencing, joining a bunch of other great open games (#Fate, #DungeonWorld, #BladesInTheDark #bitd, #Gumshoe, #EclipsePhase,#Ironsworn, and -- of course -- #DungeonsAndDragons #dnd).
