Anyone remember the old Human Occupied Landfill game? Came to me tonight that the sort of vengeful-sick-and-tired-of-smarty-players Holmeister would get along very well with your goodly antagonistic Donjon Mastar; and the characters' abilities (i.e. make shit up) is basically Donjon already (ignoring the Buttery Wholesomeness snickering Rolemaster chartiness).
Anyway. As it's written, HoL is really just a parody piece, but would be perfectly playable (and still in-spirit) with Donjon as its engine.
Edgar Sparingly just has a lot of dice in very broadly-named abilities.
