Pocket Planes Game
The gameplay is pretty simple: you need to charter planes, fill them with passengers or cargo, and send them to their destination in order to earn money. With this money, you can charter more planes to send more passengers and more cargo to more distant cities... and so on and so forth.
As you go along playing and earning money, you can unlock new kinds of passengers, cargo, planes, and other items. You'll also have tons of options available to customize your fleet of planes and create a unique airline that's completely yours.
The social options included in the game allow you to trade plane parts with your friends and compare your statistics with a global leader board. Nothing too complicated, but a good extra.
Pocket Planes is a really entertaining strategy game whose main problem is being too addictive. Don't be surprised if you end up wasting hours at a time playing without even realizing it.
