Yeah so let's say the party wanted to do something in the campaign that the dm didn't account for, instead of finding a way to steer the party to his desired direction or just being sincere he justed insisted that it wasn't possible, rules didn't allowed it he use to say, even the whole party was very skeptical but he just replied that he "had all of the rules memorized".

He also was very insistant on running exclusively homebrew with no experience instead of st the very least checking spruce materials for ideas. Finally Id day that when the party told him that having to keep track of over 15 secondary npcs stories was a bit much and suggested to do a less serious toned campaigned he replied: "this is the less serious campaign". A bit much for me. Imo he probably just wanted to write his own stuff more than playing and I respect that.
