Thats because a few good FPS games come along every year or 2 with multi-million dollar development budgets and their popularity wanes after only 18months or so which is why they have to keep regurgitating the same thing over and over.
Flight Sims and for that matter Combat Sims of note only come along every 5-10years and last for 10years plus. So it must be accepted that there are longer development cycles with a longer payback cycle... That is why the team are still working on this despite the faultering start last year. Its a long term proposition and always has been. There is still no other challenger to the WWII air combat scenario right now with this level of fidelity and detail so I expect its popularity will increase this year as the patches and sequel roles out to fix the issues we all know to well. Have patience grasshoppers!
