Few dice, few rules and more fun.
I'd go computer sim then LOL. Actually, there are a few types of combat that lend themselves better to computer sim than boardgame - and I think tactical aerial combat is one of these.
.And that means that smaller rifle caliber hits whilst having far less explosive or destructive effect in themselves, might have a better chance of collateral damage because of multiple hits that they achieve
Just noticed this. Remember, a shell casing that bursts from a HE charge is getting multiple hits as well - and most likely with a higher "muzzle velocity" due to being re-accelerated due to the explosion, and therefore more kinetic energy, giving it more ability to penetrate the armor around a pilot than a partially spent round would have.
