THE best flight sim so far, yet some bugs and low frame rates.
Top 6 good things:
Loads of planes
Nearly all controls on the planes are functionable
Over 25,000 airports
Great AI
Good enough for real flight training
Great flight lessons
Top 5 bad things:
You need at least 15gb to install the game fully!
Low frame rate on most modern day pcs
Some bugs
Quite hard to get the hang of
Some lag with online play
Conclusion:
FSX is a great game which is worth buying if you have a top of the range pc, but with normal pcs you are going to get some lag, but i would still buy it.
Also, don't buy add-ons if your pcs hard disk is small such as flight simulator x acceleration which is the official add-on for fsx which takes up another 15gb. Even if you dont have a great computer, i would still buy it. This is truly the best flight sim ever!
