People doing table top RPG, what is your favorite game system and why?

I've really been enjoying Pathfinder 2e. It's a bit crunchy, clean, and mostly comprehensible. I find it a good balance between combat mechanics and world exploration.

Powered by the apocalypse / blades in the dark. It encourages all players to storytell and the comvat/action systems aren't given hard definitions like say D&D.
