Sure, I'm not disagreeing with that. But with the wider implication that this is all that's always needed, and is always provided.
No GM will provide everything ahead of time. They will need to come up with details on the fly. And there's nothing wrong with that.
See that's awfully judgmental and overly harsh. It describes my entire 5e game that I ran this past weekend. I didn't hide salient details, but I made all kinds of things up on the spot.
A repeating refrain in this thread has been about how we're just talking about preferences here. I'm going to tag
@Micah Sweet here so he can wag a finger at you as he does at me when he thinks I'm being too judgmental about his preferred play style.
That doesn't change what I said.
Via their character.
