I play with a pretty crappy saitek st290 pro and a mouse and keyboard. The only thing there is to learn with flaming cliffs is how to use the radar for A2A combat. And even that can be switched to game mode for simple lock and fire type gameplay. No doubt the terrain and whatnot is a bit dated. The game looks pretty damn good in game and with all the new updated models and now cockpits (super stoked for 6dof mig 29 cockpit)it looks even better. I don't play this game for the graphics though so it's just a bonus.
I am speaking on the flaming cliffs series and not ED's full clickable cockpit releases such as DCS A-10c or Blackshark 2.
