So, Dungeon Crawl Classics RPG is coming out in April (not February like the poster says.) I did do some beta testing of this game, let's just say it's just brutal, you actually roll up multiple 0 level characters, and proceed into a killzone....err dungeon. If you have a character survive, then you will make it to level 1.
It's designed like an OD&D game, not the modern role-playing game, but a deadly, haphazard, monster-strewn dungeon crawl. I would definitely love to play this at cons though! Some of the best old school D&D modules were convention tournament modules.
