A non-voiced LP is not an LP in the role playing sense. I'm only interested in those.

Well, PIHwiki is dedicated to just that.
Wild Mage section.

Having watched Tord's BG1 and BG2 LP's, I have to agree. He's smart, articulate, and really brings the game "to life" through his character. As a bonus, he adds in lots of background info on the BG games, in-game lore, D&D, and various other things. I was just recently watching his NWN1 LP when it abruptly ended, sadly.

I also like Kikoskia, more for his goofiness and adding his own voices to nearly all characters in the game. At first I thought he was a tool, but his style grew on me. Pretty funny dude.

I've tried to watch others but found myself either annoyed by the narrator/LP'er or complete lack of any narration at all.

Yeah, real life happened. Around that time he met his (future) wife and got a new job with Kuma Games. He also always said he was/is not a gamer, he did those LPs in a "giving something back" way for all the LPs he'd watched -- unsponsored in those days. It's a shame, but that's life.
