I'm a huge fan of military aviation, WW2 to the modern era. I think if you're going to make a simulation game that strives for realism and dogfighting, then yes, WW2 is your only option.
But really, an arcade-style game doesn't really benefit from a realistic period setting, if you ask me. It doesn't benefit from having real life battles, real life planes. It's been done before, so why keep doing it? What's the point?
If they're going to continue making arcade flight games, I would really like them to branch out to some more fictional stuff. Crimson Skies, both on PC and Xbox, were great games. That's how it should be done. Crimson Skies seemed to take all the stuff that people actually idealise about fighter pilots and dogfights and put it into one slick package. Dogfights, absurd flight moves, flying through tight spaces, and stunts. Flight games used to be my favorite game genre. But the lack of creativity on the part of the developers really sank the industry. They refused to leave realism behind.
