This Sim is the most flexible and adaptable Sim of them all. Its the most customizing Sim in the market period. There is so many mods you can add to it and changes you can do to it that can simply leave you mesmorize.
With the capability of having different Theaters you actualy make your self a totaly different Sim that was not intended by the designer of this Sim.
For example now you can make yourself two theater of you so desire and perhaps fly in the Pacific Theater in one and after that fly in a other install on the Eastern Front in a Mig 3 vs Me106G Dogfight if you so desire. WoW!
There is another option to get rid of the stock AC if you so desire. I bet you do not want to fly or see a Corsair or a Zero Ac option in your early war ETO install.

You will need to make a folder with all the stocks sound since they are use by many addon planes.
The first method is the best way of doing it. But I
