I've been helping Catte-thulhu alongside some others beta test this system for the better part of a year now and I want you all to know its a LOT of fun. Just like any other ttrpg you need to have an idea and setting planned out, but setting up as a DM is much easier than most ttrpgs. We ran a few quick roguelike variants of it that were combat based and we were able to get everything setup and ready within about an hour one time!
We've also been running a main story based campaign over that time and its been amazing even though we've went through so many changes and variations of the rules as we figured out what felt good/balanced in the system.
As someone who plays a ton of PF2e, its a lot easier to ease into, but still has more than enough complexity to be exciting and fun to customize your characters and experiences in.
REALLY looking forward to the future of this ttrpg! <3
