HMD compatibility is a must. I've been waiting, with tens of thousands of others, for something "lighter" than DCS, and "heavier" than War Thunder that supports HMDs. Project Wingman could be that answer...well it is the answer, it just needs HMD support. TrackIR is good, and frankly from a development standpoint it gets you 3/4 of the way to HMD support; but TrackIR is 2010 tech, the advent of trackable HMD tech has made TrackIR obsolete in many ways.
Flight games IMO need to get more VR love. Sitting on the floor in your game room in a car seat chair with physical rudders controls at your feet, flight stick in your dominant hand, throttle in the other, and paired with VR so you can track with your head around the canopy - nothing has as much immersion. Hell, people are already doing that to fly actual RC planes and drones with FPV radio HMD. The fact no one has made such an easily accessible digital "simulator" of this concept is unacceptable.
A dedicated flight game with jets, missiles, flares, radar, and VR support. I mean, why it hasn't already been done is mind boggling. Because you are seated, the controls where you put them... it should have been the very 1st game to hit VR.
Keep up the great work here, and you've hit a niche that has a potential to sell a million times over.
