Re: Wesely, the Brontes, Free Kriegsspiel, every child since forever -- We do this every time we discuss the pre-LBB era. And kind of like Gary vs. Dave, it always seems like there's a tension about who gets the right amount of credit. In this case whether someone gets to much or too little credit.
Sorry for not bringing the receipts, but isn't there a quote from Gary about what they TSR was doing was convincing their audience to let them (TSR) sell them (the audience) their own imaginations back to them for $10 a pop? On some level, all of roleplaying and RPGs is just a formalization of play patterns everyone has been doing since forever. Everyone is aware of this.
Likewise, there's this thing called RPGs (now TTRPGs) that is a distinct (or indistinct, at the point we are discussing) thing -- as a cultural (pastime) movement/entity, if nothing else. That movement started with Dave and Gary publishing D&D as the simplistic answer, and a non-simplistic answer of 'it's complicated.' It had influences and quasi-forms and movers and shakers and early influencers and Wesely is undeniably one of those. His place in the games' history is beyond reproach. I think we all are aware of this, but certainly not all modern participants in the pastime are. For that reason, I'm glad to see vids like the on in the OP.
It's like Frisbee/disc -- people have been tossing around discs since ancient times, lightweight lids since they became a thing, and Frisbees since 1937. That doesn't change that
Ultimate is a distinct thing with specifics and history and notable individuals.
