A downloadable RPG System
CORE is a hybrid RPG: it blends traditional RPG concepts with narrativist techniques to produce unpredictable character-driven stories, such as those seen in popular media. The system offers lots of player agency and just a tiny amount of crunch. It's built for speed and flexibility, low prep, and high bleed.
Simple Universal Mechanic
The design philosophy of CORE comes down to this: we use the smallest scale and a simple universal mechanic for everything, both during character generation and in play. The system is built to allow quick and reasonable GM rulings without sacrificing narrative flexibility. Dice rolls and tables in CORE don't give you a number, a fact, or a pass/fail. They give you a simple prompt.
As heard on LegendsOfTabletop, MFGCast, and Fandible
In play, whenever your character attempts an uncertain action important enough to roll the dice for, the system returns a YES/NO + AND/BUT answer to be interpreted on the spot. Character traits, equipment, skills and dramatic actions are all interpreted and narrated “on the fly” as play proceeds.

The CORE system will let you try any weird thing, give you a prompt you can work with, and get out of your way.
It's easy for Players to learn, and it's easy for GMs to hack.
