Yes! Thank you!
One Roll Engine is my obsessive small-time RPG system. I’ve always loved systems where you get to roll a heap of d10s, but more importantly it has a highly expressive and generalizable core mechanic that allows everyone to roll at once without taking turns, and attacks resolve in a dynamic fashion so that initiative order, damage, hit location, and contested rolls all happen in one roll. It’s great for gritty, fast-paced, lethal combats where you can give players a lot of freedom to get creative and stay engaged. It has great rules for easily killed mooks as well, so you can quite easily have huge numbers of enemies and allies all in one battle, and it takes far less time to resolve each turn - and a far greater proportion of that time is people talking about what they’re going to do. Reign uses ORE, and that includes rules for running companies (gangs, businesses, armies, entire countries even). I’ve used ORE variants to run occult horror, mecha, low-magic fantasy, slice of life, robot sci-fi, and more over the years. It’s a great system and I can teach 85% of what you need to play in just a few minutes.
