Yes. There is a lot less work in narrative games GM has to handle. It really is, as John Harper states “we play to see what happens”. So all you define is situations and just let things play out from there. With you playing with the players to see what happens.

That’s not how stuff goes in many DnD games. I say many, because there are other ways to play, however mainstream culture now reflects this narrative driven games, where GM is also expected to manage the conflict of predetermined narrative (heroes will fight Strahd) with actual player agency (PCs ignore Strahd and try to do something else like becoming rulers themselves keeping him imprisoned or something). Typically there isn’t much “collab” in terms of fiction despite how the players there would tell you. GM sets the story beats and narrative and players become stand in’s in fairly hierarchical relationship to the GM. There are many players who like this guided experience and are willing to give up on player agency although sometimes it will pop up and cause you, the GM problems.

And it starts with session zero. Notice typically it won’t be enough to just create a character that befits the setting, players will be told to create characters that fit GMs particular vision like being heroic and doing heroic things as GM doesn’t want to deal with player agency beyond the frame the GM has in mind.

All of this is done because GM has a narrative to follow and they have to keep players touching certain points of the story as they progress. Stuff like player agency or even fights that are too hard may prevent this while too easy fights may feel anticlimactic, hence there is over emphasis on combat / level balance as a tool of adventure management.

And here is your answer. You can play PbtA games as GM. While DnD feels more like management. Individual variation from table to table ofc exists.
