What is OZR?

OZR is a lightweight framework for running OSR-ish adventure games, inspired by 2400 by Jason Tocci, Freebooters on the Frontier by Jason Lutes, Into the Odd by Chris McDowell, Mausritter by Isaac Williams, So You Want To Be An Adventurer? by Jared Sinclair, and a bunch of old editions of D&D.

It includes a very lightweight system for creating characters, avoiding danger, tracking injury and exhaustion, travel, and improving your character through experience, as well as advice for refs on preparing for play, building encounters, and running the game.

It was written by Oz Browning, with development and editing by Matthew K, and illustrations by Bert of Bertdrawsstuff.

I really dig this, OZ. Nicely thought out and explained. Great for FKR games. Nice work!



I've read going on 300 games now of several sorts but this just became my favorite OSR game I've read so  far by a pretty wide margin


Thanks! Glad you like it!

Am I right in thinking that all Saves need to roll a 1 to succeed based on PC’s starting with 1 Luck?

For a starting character, yeah.

Tough stuff!


It gets better once you survive a couple of sessions, but at first, yeah, avoid rolling!


I love the cleanness of XP/advancement here! This is a really lovely set of procedures and I’m glad to see it’s live.

Thanks Sean!
