Castles & Crusades is a fun little game that works both as a tribute to and cleaned-up emulation of old-school Dungeons &Dragons, which I've run more than a couple satisfying adventures with. Here are some files pertaining to the game.
The Pit of Bloody Thugs. A quick One Page Dungeon rolled up using a old Basic D&D book. Compatibale with C&C.
More material will be added to this section as the mood strikes me.
More information and the game itself is available from Troll Lord Games
