Quests of Legend has a nice collection of dungeon tiles for you to print out and use for your role playing or miniatures games (or both!) in a dungeon crawl.
An amazing Malifaux game table
Demon Lord is a vintage micro game from Dwarf Star. It’s now available for free as a download.
DEMONLORD is a game of strategy for two players. It vividly recreates the grand sweep of empires in conflict in an age of sorcery and enchantment. Infantry and cavalry sweep across the land to meet in battle or besiege fortresses, as winged troops wheel overhead. Priests invoke friendly spirits, as magicians prepare potent battlefield magic, or summon great beasts to their aid. And controlling it all, the dread Demonlord, and the Captains of the Hosar alliance with their retinue of personalities and special powers.
There are a lot of people out there trying to recapture the spirit of the original D&D games. For my own part, I can think of nothing that was more magical than my first excursion into the blue covered rulebook I got back in the late 1970s/early 1980s. Old School Hack is another attempt.
