#10RPGs — 1/10 Impact — Burning Wheel
There is no other non-foundational RPG that had a bigger impact on me than this. I purchased the first edition based on an RPG.net review, and it became my portal to the Forge, to my first larp (the roden one, GenCon 2004), and led to my fundamentally questioning how RPGs work and how I interface with them. Plus, I met an entire community of people, many of whom are now close friends.
This is the game that I’d been waiting for my whole life. And I’m still figuring it out!
