Combat flight simulators, like real-time strategy games, are a resilient breed which has always struggled to find its place on consoles. A mouse and keyboard control scheme is almost always preferred over a gamepad when it comes to fast-paced strategy games, and flight sims really need a flightstick if you are going to opt for a realistic feel.
Console flight sims traditionally veer into the arcade space (H.A.W.X., Ace Combat, Secret Weapons over Normandy) to try and create a fun experience for all, or try to satisfy both the arcade and simulation fanatics at the same time, usually without success. Gaijin Entertainment, on the other hand, has made some good sim-heavy console titles with an arcade feel in the past (IL-2 Sturmovik: Birds of Prey, Apache: Air Assault). With Birds of Steel, they have finally steered well into simulator territory, only offering a half-hearted attempt at appeasing the arcade crowds.
