Mercenary Mech Warfare
A complete text-only game system with no player-rolled dice, no statistics and no arithmetic. Characters are written rather than built, and everything they can do is a Power. Rules, GM instructions, a starter Powers library, a large Gear catalogue and a creature toolkit, ready to build any world on top.
MINIMAL player rolled dice. No player numbers. Just what your character is.
Mercenary Mech Warfare is a heavily modified version of Craft Text, a mostly diceless, statless roleplaying system. There is little arithmetic. A character is a concept, a background, a condition, a list of Abilities, and the Gear they carry; outcomes follow from those fictional facts.
Abilities come in four kinds. Tech covers machines and code, Ring-Touched covers Clarkean field effects and exposure-induced capabilities, Physical covers the body, and General covers professions, knowledge, and standing. Many form named chains, so Chef leads to Expert Chef and then to World Class Chef.
Equipment sits in one slot per body location, and each slot only offers gear that belongs there. There is no combat subsystem or advancement track because the Game Master handles both through the fiction rather than arithmetic.
I recommend using GPT Image 2 for a consistent art style. If you don't care about the art, then switch styles or turn it off to conserve energy/credits.
