But seriously Spit Fire...
This game is not that old. It did not burst on to the scene with complete and total availability of every single proto and production type that flew in WW2.
For their own reasons, HTC started with a later planeset. Every release sees more aircraft added. Perhaps someday they will have done them all. I hope the game and I last long enough to see that.
In the meantime, I just play and enjoy myself.
Know what? It just keeps getting better with every release.
So, take a deep breath and.........play.
Enjoy.
