It’s always interesting to me to see the overlap between OSR/Old School DMs (given previous discussion here and your tagline) and PBtA/FitD GMs. Feels like the old and new school should get along well, it’s just the mid-school like modern DnD that feels like it’s own thing.
A person would think that, wouldn't they!
And yet, they would be wrong. So very, very wrong.
OSR/FKR and PBtA/FitQ is kinda like the People's Front of Idea and the Judean People's Front. From the outside, no one is really sure what the argument is about, but we are quite sure that there isn argument and we will not let those SPLITTISTS get the better of us!
Meanwhile, modern D&D players are the Romans ... they don't even know that it's a thing, and to the extent that they do know, don't care.
NO. REALLY. LISTEN TO ME 5e MASSES! THESE DIFFERENCES MATTER!!!!!
