You can download the games you have paid for just like you did in the first place after the purchase has been made. If you're using an online website to download and purchase all the games, you will have them attached to your account under My Order/My Account section. From that location you can download all the purchased games. If you use a game manager, simply download the game manager from where you purchased the items and then the next time you log-in into the game manager, you will have the possibility to select the games you want.
