Dungeon Quest is a free old school fantasy RPG.
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.
Free for the downloading, Spellcraft and Swordplay is a professionally done “old school” fantasy RPG.
Dark Dungeons is a clone of the old school D&D game. There’s been a real renaissance in the retro style RPGs, and its one I welcome after all those years of angst ridden vampires and new-style gaming.
Party like it’s 1974!
The Microlite 74 RPG system is a slimmed down, old school fantasy RPG:
Microlite74, like its parent game, Microlite20, is a trimmed-down, sub-miniature version of the Primary Fantasy SRD rules that has been designed to be quick and easy to play. The goal of Microlite74, however, is to recreate the style and feel of that very first (“0e”) fantasy roleplaying game published back in 1974. If you are at all familiar with any game based on the 3.5 edition of the Primary Fantasy SRD, you will find Microlite74 easy to play and easy to run as a GM, but with an extra helping of “old school” flavor.
While Microlite74 is designed as an introduction to “old school” play for players more familiar with modern rules systems based on the Primary Fantasy SRD, it is a rules-lite OGL based game system that old school grognards – especially those who cut their gamer teeth on “0e” – should find equally enjoyable. It is also easy to modify with your own house rules or rules drawn from your favorite edition of the world’s most popular fantasy roleplaying game.
