I disagree here. Flying The F-15C/SU-27/Mig-29 competitive is the main part of the simmulation of those air planes. To deploy tactics better, react faster and deploy your weapons better than the other. Even in single player. When you playing this game you want to be better than the AI and other players right? Otherwise it would be a crash and burn simmulator. Or a "Fly patterns around the terrain and aim your advanced weapons at the ground simmulator". Sorry if you are not competitive in a Digital Combat Simmulator you will get splashed by every AI or player.
While we also fly like you do we also want to kill our opponent in the most efficient way before he can kill you. If you take out the competitive part you won't even have a Digital Combat Simmulator anymore. You will be gazing and turning at beatifull created switches and look around the cockpit.
