Couple things in this
I'm curious as to whether or not there's a reason for this, as it seems to be rare in flight sims; there's almost never a pilot in the cockpit?
It's nothing you usually think about, but especially since the addition of shadows the cockpit seems really empty. It's weird seeing the cockpit frames on your wing with nothing in the cockpit. It's also a bit odd, to me, to have the phantom stick and rudder pedals moving with nothing touching them. Also to look back in the Ju88 and see two unmanned guns, or in the 110 etc. Has anyone from HTC ever considered putting a pilot 3D model in the cockpit even when you're in it?
Another thing is something I was thinking about was while I was waiting for FSO to start the other night. Everything's very still and dead. The ack guns move silently and without being manned. Ambience and activity adds to superficial immersion and realism and is pretty commonplace in modern games. It would be interesting to see little animated characters in the ack implacement, just screwing around when nothing's happening, and actively manning the guns when something is happening. Jeeps and cars running around the base from the tower to the hangars etc. would give a feeling of being at an active base rather than some kind of weird ghost town. Vehicles driving around the towns and new cities would also be interesting. Just to add a sense that you're 'somewhere' instead of in a video game
Ambient noises, nature sounds like birds chirping, waves crashing and such are also things that can be found pretty commonly in most games, and that ambient noise adds to immersion instead of constant dead silence. These aren't things people think about, and if done right wouldn't be noticed, but would add a 'feel' to the game
Just a thought
