I'm an old man in a middle-aged man's body. I've been playing tabletop RPG's for almost two decades now and still seek out more creative and fun adventures. I confidently DM D&D 3.5 and 5e, Starfinder, Pathfinder 1 & 2, Fantasy Flight's Star Wars, and Vampire the Masquerade. I'll happily play just about any system that has that good balance of mechanics set in for consistency, but not so structured to be abused without a good GM/DM's guidance.
Easy going and clearly never tiring of being let down by humanity. People are best when working together to problem solve and learning about themselves in the process.
It doesn't matter if you only say things, it's what you actually do about things that matters.
