The site is linked in the sidebar to the right, but I wanted to promote Megadungeon.net as something special: a collaborative, volunteer-based design of of a large, ruined monastery and dungeon in the tradition of the early days of roleplaying games, especially Dungeons and Dragons. Even if you don’t play D&D, the maps are quite nice and easily ported to other games. There are some nice new creatures, too.
Well done.
