X-Plane

"...one of the most customizable simulations around... you are virtually guaranteed a plethora of free updates... by far the most complex flight sim on the market; it will have even the most seasoned stick-jockeys in awe of its precision."

"...not the easiest simulation on the market; the learning curve is extremely steep... made with obvious enthusiasm but lacking a lot of the polish of its market-dominating competitor."

"X-Plane is the world's most comprehensive flight simulator, and the most realistic flight simulator available for personal computers. "

"...if you want a more accurate flight model, more features, more design programs, more gameplay options, and more planes, then X-Plane 6 is for you."

"...the most advanced flight simulation available... The flight models are quite realistic... some parts of the game seem incomplete... a very flexible physics lesson..."
