Hi sqiao01, thanks for the kind words!
Honestly, I'm probably not the right person for this one, I work solo with my own material (guitar, synths, sound design), so no voice actors, no external scripts, no wrapped sessions. If a take turns out bad, I just re-record it myself on the spot.
So no real revision workflow to speak of on my end — but good luck with the research, sounds like an interesting problem space. If you ever need input on the composer/sound design side of game audio, happy to chat.
