The Mig-29
K, to be precise. Yes, it had that.
Will you finally believe it...!?
I am not certain, but I think it was not before 2.5 that aerial refueling was possible, too. For the player, I mean.
Later came LOMAC. Then the DCS series with Blackshark and Warthog. Unfortunately one already could see in the early Flanker what later titles still suffer from, imo: the sterile, non-imserive environment and playing expereince. Technically the planes they simulate are works of wonder. I just find not much fun in using them in their environments. Technically sophisticated, but leaves my heart out in the cold.
