I am currently in the middle of playing Fallout 4 and it is the furthest that I have made it in any Bethesda game so far. My biggest problem often is that I get distracted by the side quests or I get so overwhelmed with what it is possible to do that I just never seem to get anywhere. My problem is that I like to complete all the quests and find all the things, which could practically take forever in most Bethesda games.
In Fallout 4 they have really given me a sense of purpose both in the main mission and with the side quests. The people of the Commonwealth trying to carve out better lives for themselves and their family. Then there are all the people, creatures, and things trying to make those lives a little more difficult. It is driving me to want to do more, but it can get so easy to get distracted. I am curious how much further I need to go on the main quest because there are so many other things that can be done! For someone who likes to complete all the quests it is a real struggle.
