You need to model aircraft that generate excitement and will actually be used. ....
That is sort of my point. I think adding more of the lesser known WW-2 planes to the game is fine, but if you really want to get people talking, then go for a genre that isn't what we have now.
I know that the previous online flight sims (air warrior and Warbirds) have a Korean setting, but that is just two planes. The Mig-15 and the F-86. It still plays the same as WW-2.
What I want is something completely different with all new skills to master, such as in-flight refueling, afterburners, and guided missiles. Modern jets are just as popular as WW-2, then followed by WW-1, and last place is probably Korea. I would argue that Korea is even less popular than science fiction fighter games (although HiTech and Pyro did do a space combat game once upon a time....can't remember the name of it though).
If the guys at Hitech creations really want to do something worth playing, then I say go for jets and missiles.
After all, I don't know of any jet fighter simulator MMO, but I can name FOUR World War-2 flight sims you could only play online.
