I've been doing a little research into this with the old games that have this kind of approach and hopefully, some people will find it helpful.
- X-Wing Alliance - This has the first person turret view. You can switch between the turret and the pilot station on some ships. It didn't have multiplayer ships but you could set your droid to pilot, while you gun. Experience : Awful, the field of view was restrictive, the controls felt clunky and difficult to hit when the ship was evading. Ended up setting the turret to auto and just flew the ship from the cockpit.
- Freelancer - For best results, this game is played in 3rd person with a mouse. Was not immersed in the experience and it felt like an on rail's shooter.
- I-War II - This allowed you to go to gunnery view, showing an external view, while locked onto you present target. This was invaluable because the ships were bigger (i.e. x-wing fighter 14m long vs Dreadnought Corvette 200 m long and you needed the situational awareness to survive. It didn't loose the 'Sim' feel because the guns tracked proper and could only find fire if the ship was in the appropriate arc.
I think the only issue I'm going to have with the gunnery view is the 'Feel'. If it turns Elite into a Freelancer like experience, then I'll be missing out and if I see a player-crewed ship, I'll be over to Solo faster than Princess Leia says 'Where's Han?'
It it's more of an I-War II 'Feel', who want's a gunner?
