Honestly, advanced engine management will bring a lot more realism to dogfights! Not that arcade Wingcommander (with a little gravity & drag) stuff! The sole fact of overheating engines put IL2 dogfights way ahead IMO. As Wulfe said the 190 (and other planes) will be able to play out their strengthes and may live up to their RL reputation (unlike most sims, including AH).

I am looking forward to Ilyushin Online War 2 - with realistic engine managment - !
