I've used / am using these rules in four games now:
- solo play of the Barbarian Prince by Dwarfstar Games
- group play in Middle Earth
- group play of the Barbarian Prince
- duet play in Middle Earth.
Trying to persuade a prospective DM to use them for another group play Middle Earth game.
They're good multi-purpose rules that work for any not-overdone fantasy / fairy tale setting. The freeform but limited Magic concept especially works well, but the choices made in character building between combat and other skills also present some complexity that makes the rules fun to play with.
