Infinite Flight is a good flight sim, but definitely not the greatest. All have their pros and cons. Infinite Flight does have the multiplayer experience on a server, which makes a huge difference. However, people say its the most realistic. That couldnt be farther from the truth. The aircraft doesnt have any wing flex features, and the physics are out of whack. No buildings or terminals, no live cockpits, etc. instead of making more planes, the devs should focus on getting their current planes in order. With all this negativity, I should mention that Infinite Flight has the best looking planes on any flight sim. The exteriors are crystal clear, and they do look great. The engine sounds are also a plus, but theyre not totally there yet. So overall, Infinite Flight isnt that bad of a sim, but I would still opt for Aerofly 2 or X-Plane 10. Both have buildings, terminals, and jetways, and the physics are more realistic. Plus X-Plane 10 is soon coming out with a fully-functioning cockpit, where you can control all of the systems, start engines realistically, etc. A brand new flight sim is coming to the App Store as well, and based off of the videos theyve made on their Facebook page, it looks pretty promising. Seems like Infinite Flight will have some new competition.
