Companions have always been an interesting part of the Bethesda world that I never have cared for. In a way, I feel they get in the way of my "lone wanderer" role playing and almost feel like having them is cheating. I've always enjoyed clearing out areas using guerrilla tactics and having to decide what items I can carry and can't. Having a companion always just left a "fast track" approach feeling in me, a feeling I'd rather not take. Both in Skyrim and Fallout 3/FNV I always chose not to have them with me when I could.
This is not to say that I wish they were omitted as I see they are a popular attraction to many gamers, I'm just asking if there is anyone else out there who feels the same way and does not ever use them as in my playing experiences.
