Well, I don't know if I really set a new record, or if I was just the guy boring and/or lame enough to chronicle the whole thing. I'm still disappointed though, I feel like it wasn't really a "win" because I had to rely on scorpions at a few points, otherwise I was toast (noteably with Josey, of course), and didn't experiment enough with maybe survivor's curse (dunno if it would have helped, since giving her just seconds of breathing room meant watching my health go from full to zero in a flash). And I now know that I probably could have concievably not received the XP for boss and boss related kills using various tricks, possibly coming out lower in the end.
All that being said, for me it was a lot of fun and a good challenge to sort of turn the game on it's head and push my personal envelope as far as finishing the game at the lowest that I could. I'm not thinking of trying again anytime soon, because at times it was quite trying. To be honest I'm eager to get back to playing "normally." Though I am still curious to know where more corners could be cut. Thinking about it though, I think finishing much lower than 17-18 would be tough, but I know someone can do it.
