Eh. As I said, I guess I would have been the first--which doesn't mean he wasn't a wonderful GM, or that everyone who played in his games loved his games, nor does it say anything about the people who loved--or would have loved--playing in his games; all it means is that he doesn't seem to have been a GM I would have much enjoyed playing with. I have a pretty good handle on my tastes and preferences, but I don't expect them to be universal.Au contraire. Tweet was a wonderful DM, and everyone loved playing with him. He was so good, that WoTC's first TTRPG was Everway!
But most people aren't Tweet (like they aren't Arneson, or they aren't Matt Mercer, etc.).
I would have loved to play an AD&D game run by him.
