Yeah, I meant if it was fully voice-acted from the start. Then they would have to reget *all* of them for the re-write and update, or totally replace a performance.
Not to mention the amount of actually paid voiced dialogue getting lost.
It's stuff like that that sometimes makes expansions of fully VO very incoherent feeling. Like the SW:TOR I mentioned before adding a new race and still everyone in the original game acting like you're human for example cause they couldn't update it due to VO (With the most hilarious one's seriously asking what race X is when it's your own), then suddenly after 90% of the game they spontaniously discover you're not a human.
