Jim likes Torchbearer because it brings the robust and exacting Burning Wheel engine to bear on classic OSR dungeon crawling!
Torchbearer is a riff on the early model of fantasy roleplaying games. In it, you take on the role of an adventurer seeking his or her fortune. To earn that fortune, you must explore forlorn ruins, brave terrible monsters and retrieve forgotten treasures. You'll get hungry, scared, hurt, maybe diseased, blinded, even killed dead in some God-forsaken pit.
But if you make it back out, you may just do it with riches enough to retire from this lousy gig.
