Different tastes I presume. I think part of the problem is that VP is very serious and dark so the cheesy VA only cheapens the experience whereas SO2 is more comical and lighthearted so the bad VA work makes it more funny and charming.

Btw, as far as I know, Lenneth for the PSP has the exact same VA work as the original except for the new CG cutscenes. Cause its the version I played and if that is the "new VA work" then I do not want to hear the original if Lenneth is considered an improvement.
