I can definitely advise you NOT to get FSone. I did, and regretted it. If you get a perfect download and no problems then it is a good sim and the graphics and behavior of the planes is more realistic than Realflight. My computer was state of the art, I downloaded every patch and upgrade available and still had nothing but glitches and program lock ups with FSone, and there is NO PRODUCT SUPPORT for FSone. It's a shame because in my opinion, when it worked it was a better simulator than Realflight, but it is unstable and in my case became totally unusable.
