Cypher System
The Cypher System is one of those catch-all systems that features just the right balance of “roll lots of dice” crunchiness and the ability to improv narrative beats at the table. It’s got tiered skill set for a modular chargen, which means you can use whichever best suits your character and work your way through improvement. It asks players to roll a D20 to perform a difficulty check for most anything, and combat damage is universally assigned as either light, medium, or heavy. The Cypher System also has an open license.
