"All RPGs are descended from wargaming by virtue of D&D" is a trash argument. Full stop.
Seriously, I have a treehouse and some toy dinosaurs who will fight you on this.
Yeah. It's one of those arguments that quietly bakes in redefined terms in order to be "right." It's the tabletop gamer equivalent of "2 + 2 = 5 (for sufficiently large values of 2)".
@megueyb I mean yes, but it's just for the fact of the word "All" used in front of rpgs. I would say "most commercially available rpgs", and even then much of the joy of rpgs is that fertile middle ground, somewhere between rules and imagination. There certainly is a strong element of a "single-unit wargame" in many rpgs, but it's not the only element, nor is it in every single rpg. My issue is with the word all.
Absolutely spot-on.
@megueyb Also....... so what? Yes, D&D had a huge influence on RPGs, much like how Tolkien had a huge influence on fantasy. Everything in popular media draws on something that came before it, and some things are drawn from moreso than others. What would someone gain from arguing that all RPGs are descended from wargaming?
