I find that a consequence of this style of play leaves little surprises. Both in terms of what a perk will do or how a weapon works as well as what consequences of my action for some quests are going to be. So I've kept myself from doing any sneak peeks at the DLC just to see what kind of trouble I can get into when I don't know the roadmap previous to the encounters. I'm betting I'm going to miss some carrot that will leave me gritting my teeth a bit but at the same time that leaves me something to look forward to on my next playthrough.
