Paper Dungeons - yup, it's the best R&W dungeon crawler!

About Paper Dungeons: A Dungeon Scrawler Game, from BoardGameGeek:

Prepare your adventurers for a challenging dungeon exploration in Paper Dungeons, a roll-and-write game that seeks to reproduce the feel of a dungeon-crawler. In the game, you control a classic group of medieval adventurers: warrior, wizard, cleric, and rogue. In each of the nine rounds, you select three of the six rolled dice and use these results to raise the level of your characters, produce magic items, obtain healing potions, and explore the dungeon to face challenges and collect treasure. You'll also find three large monsters waiting in the dungeon, and you can fight them for glory. In the end, whoever collects the most glory wins.
