I have been introduced to a Powered by the Apocalypse style fantasy game called Maze World. Here is a link to it on Drivethrurpg
Maze World on DrivethrurpgIt is a really cool adaptation of fantasy tropes. It has things that a DnD player will find comforting, and enough variety in character classes and character growth elements that it should make for a good long term adaptation at the table.
Check out a review if you are curious, though for under $5 it is a pretty good buy. Way better than Dungeon World.
