Tabletop Roleplaying Framework // v1.0

S.P.A.C.E.

WAIT?! WHAT IS THIS??!?!1?! IS THIS A GAME?!? CAN I PLAY IT RIGHT NOW WITH MY FRIENDS?!?

Yes. Yes you can. The S.P.A.C.E. System is a lightweight, genre-agnostic tabletop RPG built to fit on a 3×5 card and run entirely off vibes, five stats, and a fistful of six-sided dice. It works for space opera, pulp adventure, hard sci-fi, or whatever your table decides it is halfway through session one. No character sheet longer than an index card. No math you can't do in your head. Rulings beat rules, the dice make it exciting, and if you can justify it, the GM should probably just let you try it.

Below: the core rules, seven ready-to-play characters, and everything a GM (human or AI) needs to run a session tonight.

The pitch, if you need one more push

Roll a number of six-sided dice equal to your stat. 4, 5, or 6 is a success. 1s cancel a success. Get enough successes, you did the thing. Don't, and something interesting happens instead. That's basically the whole engine — everything else is just what you decide to point it at.
