Its not surprising its done so well, its only got 4 islands and is online only, so its about a quarter of the price of a normal game, but has the graphics and gameplay you expect from a current gen console, unlike so many of the downloadable games.
It uses the same game engine as Battlefield:Bad company, so anyone familiar with that on the consoles will be able to get into this straight away.
The only thing I dont like about it at the moment is that the planes are bloody difficult to control.
