The map looks and feels amazing, one of my favourite worlds in a game, and the main story missions are really, really good

BUT

To unlock said story missions you have to do multiple hours of open world tasks, most of which consist of going to an area and mindlessly killing everybody. If you enjoy grinding, you will probably like it, I have a friend who does, but I couldn't bring myself to finish it because I found unlocking the story missions mind-numbing.
