What I like about the current state of the game is that there is something for everyone. The arenas, the aircraft/GVs, the plane sets...ect. It seems that no matter what you want to do there is somewheres to do it.
I'd like to see more Historically correct missions, and more Historical correctness, but I just dont see how you can create a bunch of rules to enforce it while keeping everyone happy. Its not like I expect anyone else to have my wishes for the game. You cant enforce historical correctness with rules if the very rules turned off a large slice of the player base. And it would.
Cause a large slice of your player base wants to simply furball in whatever airplane they want at the moment. Start telling them what they have to fly, and what they have to do, and what year they have to do it in, and your going to have a whole bunch of people looking for another flight sim.
