Yeah bjon045, i think you're right, i also remember the auto answers were editable, so where Duke would say "come get some" or "a piece of cake" you could put in your own wav' file inserts. I remember experimenting with some shocking and unmentionable expletives!
But the main point remains, those "Duke Nukem" type games from earlier years had the ability to be varied or edited only because they were "shooters" and used repetitive lines, whereas in games such as the gothic series where the dialogues contain 'critical paths' to quests, then it would be inpractical to edit just for cosmetic reasons.
Therefore this is where the developers should insert and 'mould' the in-game atmospherics at source, like peeing, scratching, stone-kicking, apple-eating, beer-drinking, small-talking, yawning, hand-waving, beckoning....they're all there in G1....where the original atmosphere began.
