Hi guys,
The best flight sim? It depends, if you are looking for an arcady game with little realism, yeah go for novalogic and that other stuff. Let me tell you now ive played sims for a long time. The most realistic flight sims with awesome graphics are Lock on Modern Air Combat and Falcon 4.0. Falcon is a bit older but with new upgrades its still great. These wo sims are hardcore and to play you will need to do a lot of learning on how to control the planes before you can fly. Once you do, the flight experience is amazing and very realistic.
p.s. if you want lock on, have a good pc because its one of the latest sims out there.
