Later some of them were more like 'fetch' quests, but there are plenty of interesting one. Literally when you walk to make one quest, you come back with 3 or 4 more to do. The open world to explore is amazing in this game. There is also a good twist in a main story which kinda makes you later guessing your actions. I loved the story of 'Fallout 4' - it was better then 3rd games.
And although 4th part did not improve on graphics - for this date and age, the game looks OK / good but nothing more, it did improve on almost everything else. I had big expectations for 'Fallout 4' because 3rd game was probably one of my all time favorites. To think that i have invested around 100 hours of my life time into 'Fallout 4' (2015), done the main story, made A LOT of side quests and the there is still A LOT to explore encourages me to safely say - 'Fallout 4' is a great game.
