Well yes.......a game engine designed to render out to 20 ---------123141241 kilometers is going to look bad at ground level. Thats a given. However it does work quite well for 50 meters off the ground and above. Yes i think they may have stretched out to far on aspects of this one. But combining legit air craft sim with some sort of armor sim is just a matter of time. ARMA series does not really count on this.......not capable of the really long visual ranges needed or an aircraft. It sort of is but not. Gawd awful armor simulation.....messed up flight dynamics. Does infantry VARY well however.
However just because you can do something does not mean you should. While many people dream game is combining infantry armor and aircraft into one game. Well to do them real world even if the tech is there, there is next to zero way a company could get everything legit.
Hay I am a bad fly boy.

But I am a rotor head......flying tank baby.
For instance gravi should never attempt to add playable aircraft in current engine....would never work well. Dont think they want to either. But they could turn an armored sim into infantry combat without it being to horid. #1 issue would be throwing your face into brush and realizing that it is not up to your latest greatest FPS level. As that is what it would be compared too. However, its not far behind at all. Oh and the morphable ground would more than make up for it. But with that said........IMO it would be better as 3rd person overall command of infantry as a tactics sim in the "brush". But all this does not matter one bit as I have totally gone off on a random stream of thought.
