# RPG a Day 2023 - Day 18: Your Favorite System tags: #thoughts/RPGaDay/2023 ![[RPGaDay2023.png]] Of all time? I suspect that I have to go with **[[Wushu]]** here, purely because I know that I can use it for any context, for any setting, for any situation, and it only has one serious drawback: it's not GMless. I love it so much, though. I think it was the first game I owned that really leaned into "whatever you say in the course of play is exactly what happened." It's amazing how much of a difference that makes.

It's a hybrid wargame/RPG system that is playable solo and co-op, and I have hacked on it, used it, manipulated it *so* much over the years.
