This is freaking awesome! Do you mind if I going to translate it in Italian?
A downloadable game
SPACER is a minimalist set of role-playing game rules for running old school science-fiction adventures, inspired by and compatible with KNAVE created by Ben Milton. Tweaking the rules and creating your own exciting science-fiction universe is expected and encouraged.
Like KNAVE, SPACER features:
Compatibility with most OSR-style games. Weapons, armour and especially creatures & traps can be used with few, if any, changes.
Fast to teach, easy to run. Especially suited to games with new players or one-shots where fast character creation and few rules are a bonus.
No classes. Every PC is a Spacer, a galaxy- hopping adventurer at home in space as much as planet-side with a bag full of tech to help them. A PC’s role in the party is determined largely by the equipment they carry and their attitude.
No skills, all d20 rolls use six standard abilities. Any PC’s without the skills to survive in space are already dead.
Optional player-facing rolls. Spacer allows Referees to run a game where players do all the rolling. Switching between the traditional shared- rolling model and player-only rolling can be done on the fly.
Credit Standard. Everything costs credits, every- one gets paid credits. One credit is the same as one copper piece in Knave.
