Microsoft CFS III definitely had issues, but CFS I and II (have 'em all) are still pretty nice combat sims, especially if you're looking for WWII-era fighters.

MS Flight Simulator X ** (have it), and from what I've heard, the X-Plane series are good if you want to practice some real-world instrument work, approaches, etc., or just want to do some simulated airborne sight-seeing...

** As demonstrated in Doc's post just previous to this one!!!
