I've been playing in a Discord server for the past few months of a game called Road To Yokozuna. It's a homebrewed system where you create a rikishi (Sumo Wrestler) and make your way through the ranks in an attempt to get to the fabled rank of Yokozuna. Every other month they'll have a Tournament, just like Grand Sumo, and a Banzuke where players are given promotions/demotion based on their performance in the previous Basho.

To make a Rikishi you have the skills: Power, Weight, Footwork, Skill, Spirit. They each start at level 2 and you have 5 training points to adjust your stats as you see fit.

For the actual matches, each rikishi will send their planned moves to a third-party Gyoji (referee) who waits until he has both players' moves and sees the round through. Quick Bout Guide

The Offense/Defense system is set up in a bit of a rock/paper/scissors system, but you're still rolling dice. I cannot explain sufficiently the pain of correctly counter-picking your opponent's move, only to have the dice fail you spectacularly.

If you want to check it out, the Discord link is https://discord.gg/eT5rkeY and tell them Tsukizakura sent you. That's my character and you'll recognize him by the hairline fracture in his arm and the concussed look in his eyes.
