In my mind that would mostly be "What you see is what you get".
There are not a lot of downtime when I work normally. Few seconds hangup when I save because of Perforce but apart from that it's pretty straight forward (except when I crash... haha).
Edited videos, IMO, would be for official tutorial if the mod support stretch goal is achieved.
My idea would be basic like that. We announced it a few days before and then camera on, twitch on and go. During a few hours.
There could be potential spoilers for sure but I'm pretty sure we could work something out ^__^
@Lacrymas, good point of view. That's why I'm asking. Maybe that's a bad idea after all. I know that some artist stream themselves while painting for example. So that's why I had this idea. There was stream live, in the past, made by Larian about how you do stuff in the editor. People were asking for stuff and they would do it.
I guess that could be the same.
