1. Never purchase version ONE!
2. Always go with market share!
3. Spend a little extra for the ability to UPGRADE!
Disclaimer: Since being here at the UCF Institute for Simulation and Training I have been able to research information dealing with Flight Simulation. The compilation of the following pages are a combination of data found on the Internet and compatibility testing performed by yours truly. I would like to express my grateful thanks to those who went before me and have web pages on this subject already. On the Flight Links page I have listed all their links as well as others I found to be very helpful.
