I'm playing AC:B on the pc right now and I'm LOVING IT! I think its a big improvement over AC2 which I also enjoyed. I stopped short of solving all of subject 16's puzzles in AC2, I also don't remember much of the video as well and I don't think it had an influence on my understanding of the AC2 universe. I've already stopped caring about subject 16's puzzles in AC:B seeing how the actual game is just so much more fun to play. Seeing as I can just youtube the "Truth" if necessary for both games, should I still attempt to unlock all the videos?
