The purpose of dcs is to eliminate inacuracy and promote detail and accuracy, surely you would agree they are privy to MORE infromation about the MiG-29 than the MiG-29SMT because the information needed to accurately model the MiG-29 is de-classified?
As DCS's objective is to provide gamers with the accuracy they desire, they would be better served bringing out a model like the MiG-29, regardless of whether it is in service or not, than the MiG-29SMT because they have the information required to accurately model it, and accuracy is what the game promotes.
I personally would prefer to have an older model like the MiG-29 modeled ACCURATELY in the short term, over having nothing or inaccuracy.
Good things take time RedTiger, wouldnt you like to at least fly an accurate and detailed MiG-29, even if it is older, while you wait for an accurate model of your precious SMT??
