Sorry jhfighter2, but I don't understand your post or your indignation. If you want to play a game / fly a SIM where everything is just like it is in Flanker 2.5, play Flanker 2.5. (no ???)
Yes - he can say that Flanker 2.5 & Janes are both unrealistic because they ARE - they're the developers interpretation of data from reality tempered by allowances for gameplay, simulated in a game... He can say FC is "more" realistic because while they're all just approximations, on the basis of his research he reckons this one is the more accurate.
The fact that 2 other SIMs are more like each other than FC is neither here nor there. The old flight modes in FC resemble those of other sims more than the AFM's for the SU25 & SU25T, that doesn't make the old models more accurate than the new, just the way things used to be done.
Is ther eany challenge to be had in the game ? If you want a bit of a challenge load up the SU25T with gas, stick A2A's on the 4 outside pylons & guns on the inner then go & find yourself an F15 to play with.
