Oh really? Presumably you mean 767 and 777 types?
On the subject of PC games - a friend of mine, a 747 skipper, had great diffiulty landing the FlightSim 747 but I could do it most times out of ten. On the other hand, he was a dab hand at TRACON (ATC sim) and when I tried I had about 25 mid-air collisons and the wreckage was strewn everywhere! PC games are fun, but that's all they are and can in no way approach the real world.
