This is what I was looking for in an online flight simulator game.

1. Is the Game compatible with your OS?

2. Is the game updated regularly?

3. Does the game come with clear instruction manuals so that you can get actual flight simulator lessons?

4. Is the sim software realistic? Points to check for - accurate runway markings, realistic terrain, airports,airplanes and helicopters?

5. Can you adjust specific features of the flight so as to create many variables thereby challenging the pilot in varying weather and wind conditions?

6. Can I fly both aircrafts and helicopters?

7. How many aircrafts are available to fly? - Are there more than only combat flight simulator airplanes?

8. Can I set time zones?

9. Is there good support for the software?

10. Does the software have add ons for flight simulator yokes and other external devices?

Once I had all 10 points checked on my list and was satisfied that the flight sim software was indeed going to be worth the cost, I settled on a final product.
