So, there's some dude/jerkface who has already posted six YouTube videos of a Dark Souls 2 walkthrough. I was interested, but didn't want to totally spoil everything for myself, so I elected to watch just the first video -- which is about 45 minutes -- on the theory that I would've seen most of the areas already from other preview footage. Luckily, it turned out that this was pretty much the case, although there is footage of the first boss in it. And obviously it gives a much better sense of the way the world is connected in the early game.
In any case, I'm embedding the video below. If you don't want to spoil anything for yourself by seeing footage of the first 45 mins or so of the game, don't watch.

BTW, if anyone cares, I can provide some info on the starting gifts.
