Flight simulator players are something of a different breed. Flight simulation games can require hours of attention to what, for many people, is an extremely tedious (boring), monotonous (boooooring) task. But, the best simulators on the market are so good (realistic) that you can actually use them as part of a professional flight simulator. X-Plane (for the desktop) is that good.
Now, the Android game is no substitute for getting your pilot's license, but Laminar Research, the company that makes the game, promises "85% of the accuracy" of the desktop version. Which is amazing, considering just how much less hardware horsepower you're dealing with on a smartphone compared to a modern PC.
