Cortex Prime is an incredible effort from designer Cam Banks. This new 2020 edition accomplishes both fusing together the three previous Cortex Plus systems (Smallville, Firefly, etc.) AND also giving common throughlines to the system tools, provide dozens of ways to adapt it to create the type of game you're group is seeking, and updating and smoothing out the rules themselves to be more intuitive.I absolutely LOVE how Cortex Prime is a perfect mix of embracing both a system that is very narrative/roleplay based, retains a nice structure and low-medium level of crunch (more than Fate, maybe comparable to a Genesys), and highly adaptable for each game table. If you want your game to be more D&D/Pathfinder like, it builds in flexibility for that. More Fate or Numenara/Cypher like, it provides toolboxes for that. It's truly flexible, and once you basic foundations are grasped, it becomes very intuitive to play with.Highly recommend this to anyone seeking more narrative based systems with intuitive crunch than only rules-lite!
