Wouldn't be a big ownage-factor if we could script the briefings as a separate .fs2? So instead of that map-screen, we could have a mission, tagged as without briefing nor debriefing, AI-controlled Alpha 1, invulnerable and set to be ignored by everyone, and a whooooooole lotta waypoints. The HUD would be a problem, unless we can have voice-acting - toggle-hud makes the message-text go away, but a voice-file will apparently play.
This will sort of obviously mean that the briefing in the actual mission-fs2 will have to be non-existant. And loading-time would take away some of the wow-factor, unless it can be dramatically reduced somehow...
What about it?
