Not just you. I don’t remember which Fallout game I got, but it probably wasn’t the first, and I got to like the second objective where I’m supposed to help some settlement restart their power generator by finding some part, and I realized I was too bored to continue. It was like I could see the entire game stretched ahead of me as more of the same.
Not all games are for all players, so I never thought “Fallout sux”; it just wasn’t my bag. I think the Fallouts are micro-farming long-winded objectives for really small benefits; I guess a lot of people like that, but it’s not for me.
