GameHouse is a digital-download game service. It means that they do not make discs with their games. They use a game center application you can use to download your games. Upon buying a game, you will use an email and when the order is processed and finished, the game will be attached to the email. This is extremely handy in cases when you performed a recover of your system and lost all the games and other information. You can then simply login into your account, and download the game because it's already bought. It is much easier and more convenient in this way.
