I don't understand why some people say that Fallout 4 is too short with too few quests, leaving little to do. I have a list of all the quests. It shows 184 quests. If you're having problems finding something to do in the game, search the Internet to find a listing of all the quests and stay involved. Also, you can play the game several times by siding with a different faction each time. This approach will enable you to play all the various quests and to stay busy.
