Almost all of the story missions are: 1) walk/drive/ride to this place 2) Talk to NPC 3) Do an extremely boring task (follow someone, drive somewhere, etc) 4) Walk somewhere else 5) Talk to someone else. 6) Collect XP or another reward.
Most of it is not enjoyable gameplay.
Yeah. Like, the train heist and other cool gameplay segments were fun. But the missions to go to some random town and talk to someone and escort them back? Horrible.
Don’t forget the top notch drawer rummaging simulator.
