Blizz showed you these? Man, I pity you.
Incidentally, I love the first video you linked (Rose). The woman who's supposed to have an accent? Loses it entirely for her first line. Oops. Also, her line makes me start thinking of dirty things for some reason. "Galahad, you came." Could she please try NOT to sound awkward?
This is the main reason why I'm not going to consider voice acting in games to be a serious thing. Ever. Thank you, Aveyond, for ruining that aspect of gaming for me forever. That and a few other lines. This is my store. What am I fighting for? What is this ominous light that threatens to engulf us?
Man, classics.
