It's strange. Even though we're all just people, seeing somebody post in a forum or chat and then hearing their voice or even seeing their face somehow seems thrilling to me, as if they're somebody famous or something. I dunno, weird.
I watched the first two vids and I'll make a suggestion, if you like. One of the things that appeals to me in watching Let's Plays when people play story games (and CRPGs are about the only games I play) is not only when the host actually gets into character, whatever kind of character that is, but goes on to explain WHY they make the decisions they do. I always find it fascinating to know what's in their head at any given moment; why they did this instead of that, what they think about the situation, whether they think A is trustworthy or kinda shady. I'd like to hear more of what you're thinking during your gameplay and why you make whatever chioces you do. I think it really draws the view/listener/reader in more and makes it more engaging.
I still remember a thread of a gamer on a blind play, talking about how he was suspicious of a character who turned out to be your best friend. His false assumptions and misinterpretations, planning for things the rest of us knew weren't going to happen, made his play refreshing and interesting.
I'm in for a copy. : )
