Neutral Evil in fact. I've been spending free time this week using a voice synthesizer to add a voice to previously unvoiced lines in Baldur's Gate II. I chose to do a certain pivotal segment of Viconia's romance subplot first, because it was one of the more memorable to me.
I'd be lying if all the talk here around having voiced and unvoiced characters didn't cross my mind a few times while doing this. I've considered using some of the voiced lines from Tav to play around with the dialogue in BG3, but that might be a little forward. Especially considering the game isn't even released yet.
I'm really excited to see what 'A.I.' does for video games in our near future. RPGs will have the most to gain from them, and we'll likely see it first in the modding community, as long as the tools aren't kept out of their hands.
