I kind of botched my game. Well, with the main quest, at least. I screwed up the Wild Card questline, which is the one I wanted to do. It's also too late to do the Caesar questline, so I'm doing the NCR questline. I got up to the mission where you have to blow up the BoS in Hidden Valley. I heard there was a way to peacefully negotiate in this quest, but I screwed that up too.

I'd rather not just restart my character; I already put many hours into her (I think I'm currently on 80 hours). I wouldn't mind losing my reputation, or even having to restart ALL quests in the game, just so long as I can keep my character.

So, I was wondering, be it through console commands or mods, is there a way to restart the main quest?
