um... i kinda doubt it'd take that much space, otherwise there wouldnt be very much voice acting in the game... they said there are... i forgot how much exactly... 40,000 - 70,000+ i think... lines of spoken dialogue.
if voice acting took up as much space as you think it would for ONE character, then this game wouldnt be a game at all, just sounds. <_<
Um. Consider the fact that most of those lines are probably part of conversations with the dovakiin... Even if dovakiin only speaks one line for every 5 that's still 8,000 - 14,000+ lines if you're right about there being 40,000 - 70,000 lines... And that's if there's only one conversation option. And there's usually at least 2...
And then they'd have to record all of those lines for
at least 2 dovakiins, male and female.
