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.

Blaster Simple Science Fiction RPG
From the author:
Blaster is a generic SciFi RPG in the 26th century where mankind’s unity has been sundered by war and where a few good men can still make a difference.
More like Firefly and Buck Rogers (the 1930′s version) than Star Trek you will form a team of adventurers who have a small starship which they can use to explore, travel, trade and fight against the dying of the light.
As usual both the core rules and the setting are single page affairs and are completely compatible with other titles in the Dead Simple RPG series.

Under The Moons of Zoon Free RPG
Under the Moons of Zoon is a John Carter of Mars inspired free RPG.
The author writes:
Under the Moons of Zoon (also UTMOZ) is the grand child of a previous project of mine Kalevala.
Kalevala was originally born in 1991 as a one of many cheap italian role playing, live action and board games collectively known as “Giochi del duemila”. Of all these mini-games Kalevala was chosen to be published in Kaos a games’ magazine published at the time by Nexus Games.
Kalevala used a sort of universal mechanic based on 1d20 and used a free-form magic system simialr to that of early versions of Ars magica.
Later on -circa year 2000- Kalevala got translated to English and completely revamped to use only d6s for publishing under Demian Katz’s Aegis.
While rewriting kalevala I had the distinct impression that the new system had potential, and already at that time I had a compulsive need to write COMPLETE rulesets, as complete as my beloved D&D Rules Cyclopedia.
UTMOZ was born from the revamped system for Kalevala, adding psionics, weird science and much more and removing magic. The main inspiration for the background setting is John carter of Mars by Edgar Rice Burroughs.
