Anyone else notice that Tchernonbog in the opening FMV sounds a bit like the Guardian from the Ultima series? Maybe it's the same voice actor?

Tchernobog was voice acted by Jace Hall.
Wikipedia says the Guardian was voice acted by Bill Johnson

edit: acted, not aced

I guess they just used a similar voice filter. It's like how Microsoft Mary sounds like GLaDOS if you listen hard enough, probably because that was what Valve overlaid over Ellen's lines.
