I would like to have a playthrough of Skyrim where the dragons leave me alone. Can anyone help me with this?

It probably has to do with the dragon aggression to PC set to zero.

4272806 , Find someone to make a mod for that. Nothing from directly inside the game itself will let you do that.

4272847 Is there a dragon faction I could add myself too or something like that?

I think there is something like Testicals the Debug Centurian from Fallout in Skyrim but I can't remember :/

That's simple! Just don't play through the Bleak Falls Barrow quest! Don't get the Dragonstone. Then the dovah won't come.
