I have FS
2002 and i think it's pretty good. Before that i had FS
2000 and that was good too. They improve things with every new edition. I think it's useful as an IFR training platform. All the NAV instruments are real and work properly. I sometimes practise ADF tracking, ILS approaches, VOR approaches etc and it is quite realistic from that point of view. It's more than a game, i think it sits somewhere in between a recreational game and a real simulator.
