For me, having to unfold wings would be most interesting in that I would experience, to the degree possible in a simulation/game, what the pilots of those planes experienced as they sat in their cockpits while the action took place.
Is wing fold/unfold anything close to necessary for a game where your primary MO is to launch and die, rinse repeat...capture fields and reset maps?
uhmmm....not even.
Still, would be a good whish for me to have added.
