X Plane will be coming out later this summer. Usually they just start out with the vanilla version of X Plane, later on they will bring all the other versions over, including a military one. As of now, I think the only game that approaches being a flight simulator is Skies of Glory, although it's a WWII action type flight sim. Great graphics and runs great!
I have it. Graphics are not... shall we say... high def. Especially when you are on the ground. There aren't any 3D structures, other than the terrain, and the aircraft carrier if you use a military aircraft. There really is no quality sim for any OS. Also if you want more planes/helis you have to buy them individually at 99 each, which can add up quickly... if you would like to know more ask me or go to the app in the Play store.
