Gameplay: Numenera is rules light, and less simulationist. Gameplay focuses on one-use powers called Cyphers that are doled out by the DM. Skill checks rely on spending points from point pools instead of static skills, which give the game a boardgamey feel but makes combat very attrition-based. Equipment is minimal and very fantasy-styled. Firearms are completely absent. Hacking is not a generally a thing. Theme and World: Numenera is a game about hope instead of existential danger. Humanity is on a trajectory to prosperity. Horror themes aren't typically front-stage, but a horror theme guide is included in the Numenera core. The world is broad-strokes fantasy with sci-fi gadgets. Almost no serious political factions and a very escapist feel.
