Hehehe. Bottom line is, you are not going to please everybody all of the time, ever. Yeah, of course we all want as "realistic" a sim as possible, while we (lets face it) overgrown kids pretend to be WWII fighter aces sitting on our arses in front of a Monitor screen....wife/gf kids nagging in the background demanding you put up those shelves
Why do we do it? Because its FUN of course! Some people however seem to be intent on sucking the fun out of everything, treating a 5Kph perceived inaccuracy like a matter of life or death and of global importance, possibly even a threat to Civilization itself lol

. These people will never let go of their grievances, real or imagined. For the most part, despite its faults (programmers of course being HUMAN like everyone else) IL-2 does a good job in terms of general accuracy.......Yes its right to aim for perfection as I'm sure they will do, but it will never be attained. Thats all.....Oh and did I mention its "just a game" ? (TM)
Carry on, you crazy kids!!
