I exactly know what you mean, I also love the exploring stuff. I just hope that you will play my upcomming hololive game because I just plan to break everything entirely by having excessive and advanced mechanics that have never been used before in that shape and form that I plan to. I think I partially succeeded with it in my first hololive game (examples: Sanity Manipulation, Layer targetting and Waiting Rooms). I personally have still to learn and explore more, or invent/reinvent stuff properly, like I know that my Sanity Manipulation was semi impactful and I def plan to bring it back in a smaller and more compact game so it has more impact and players interact with it more aside of just thinking of it like "another SRM mechanic".
I can just say that your YGO game back then def pushed my interest in going overboard with my own roles. And thinking back you did something very interesting with the concept of having roles not just be roles, but have the cards expand on it and the possibility to have different RNG sets and gain new cards or exchange them so your role builds up throughout the game and expands continously.
I mean that idea isn't new at all, but it was impressively done well back then.
I hope we can pay back each other and you sign up for an upcomming Rej game, you can fully explore it as you want to
