yea early war fighters not more for ww1 which at this time has almost nothing to offer cept numerous shoot downs by Dr1s.
You're willing to wish for early WWII but not more WWI (even though you admit you are a devoted fan of such through another game)? This is something that's probably doable with enough support. Let me add that I'm all for earlier models (of which we actually have more than a few in the game already). I'm an advocate of a Spanish Civil War planeset/terrain/arena ... though whether it'll bring in more profit for the effort is questionable.
Community influence on game development is a funny thing. Sometimes lots of noise as given over requesting something that, once it's added, doesn't fly, doesn't add more customers and wasn;t worth HTC's effort. It's a proof-pudding thing.
I'm willing to bet customers flying more of the early WWII models and flying in the Early War arena (as well as the WWI) would lead to development being focused on both. And sometimes supporting other interests can bring in support from that segment of the community for your own wishes.
