I always liked the EAW-style campaign mission briefings. Yes they were short and simplified but they really helped the immersion factor. While you studied the map there was a murmur of voices which died out as the CO got into his stride...
So I was thinking, maybe the same could be done for FE, by replacing the 'CampaignScreen' wav file with a verbal briefing. As you can't make it mission-dependent as in EAW, it would have to be a bit generic. So to avoid boredom after the first time, you would need multiple versions (plus a set for each nationality you could swap in or out manually or using maybe the JSGME mod editor). It could start with some EAW-style murmering, then something along the lines of "Right, chaps, pay attention now. The names for today's show are on the roster, so find out who you're up with. Don't forget to mark up your own map with the route. Note the bearings, speed and altitude for each leg - anyone who gets lost will be buying the drinks in the mess tonight, if the Huns don't get him! And I hope you have checked your belts are clean and properly loaded -the Armourer's life doesn't depend on your Vickers working but yours will! See you outside in 5 minutes - and good hunting!" You can see how it would be possible to produce multiple variations of that sort of thing, maybe with a bit of banter between pilots - a bit like you got in Crimson Skies, which did that unusually well, with a good deal of tongue-in-cheek banter between Nathan Zachary and his air pirates, which brought them to life!
So, does anyone know if you had, say, six different wav files in the Menu folder, all called "CampaignScreen.wav", would FE (a) crash (b) play just one or © pick between them more-or-less at random, so you got the variety? I suppose I could experiment and find out. But I daresay somebody has already tried this sort of thing and knows the answer already.
Another possibility, requiring just one track (for each nationality ideally) would be something to replace the pilot record screen music. Maybe based on the EAW nissen hut concept, where you had radio music, bedsprings creaking, and a bloke coughing, with a flypast engine sound every so often. Scratchy period gramaphone music, or maybe an RFC singsong like "The Only Way" in 'Aces High', some tinkling of glasses and other background noise or banter like you were in the Mess with the boys, an engine starting up from a test run outside, just something to give you the impression you are on a WW1 airfield, not staring at your monitor.
