Totally immune to MP. I have no friends, none of them plays flight sim, I play the game the way I want, at my own pace, enjoy my own win and failures. I have games which have great AI, and play those when I wish to be on my own. I don't want friendly fire on myself and on others
It was called Warbirds, irrc. Because I was there with a friend, and constantly get slaughtered. Then we moved on the Flanker 1.0 (Yes, I am this old)
