Multi-Genre
Cortex Prime handles a multitude of genres from books, television, movies, and video games. Almost any genre you can imagine can be represented with this system. You can cross genres, mixing them up and using traits and elements from more than one in your game, as you like.
Modular
Cortex Prime isn't a fixed set of rules. It's more of a toolkit, or a big box of building bricks. From a central system of dice and descriptive traits, you can assemble your own game from modular parts (called mods) to best suit preferences and the way you and your friends like to play.
Session-Centered
Cortex Prime is designed to suit groups of players who meet together in person around a table or online around a virtual tabletop, ready to collaborate on a shared story. Each session of play is its own experience. String a few sessions together and you get a story arc or something more episodic.
