My favorite thing about this game is how easy it is for new players to pick up. I'm an experienced GM that runs about 15 one-shots for strangers annually and this has quickly become one of my favorites to run when I know there will be a lot of new to RPGs players.
The mechanics are easy to parse and the character sheet easy to read. The tropes of the game are easy to explain and easy to sink your teeth into. And the core gameplay lets me, as a GM, throw anything at the players based on what they're doing in the moment and have it be fun for everyone.
(As someone who's played in a long campaign - it's a lot of fun too!)
