No, I like the Argonian NPC voices. But the PC's voice (as in, YOUR voice) as an Argonian sounds /completely/ human when the NPC Argonians' don't.
This pissed me off when I tried to roll an Argonian... His Fus Ro Dah sounds exactly like a Nord's.
But yeah, sadly Skyrim isn't really a multi-culti province. Like 80% of the population are Nords.
I found it really hard to play any race other than Nords for the first week or so, now it's growing on me.
