CORE

CORE is a hybrid RPG SRD: it uses trad concepts & narrativist techniques to produce character-driven emergent story. The design focus on simplicity, speed, and improvisation. Everything is on the same scale. All actions use a single Yes/No/And/But mechanic. Results are narratively interpreted. And it was built to be hacked.

CORE is the system underlying the bestselling game "DayTrippers," stripped down to its fundamentals and ready to be skinned for your setting. Published under the Creative Commons Attribution License, you may use or modify these rules for your own games, either for free or for profit, simply by attributing the CORE system and author within your work.
