Basically, GameFly is similar to Netflix, Blockbuster, or any other online rental service. You select the game you wish to rent. When the game has an availablility status of Available Now, the game ships to you. You'll recieve the game roughly 2-5 days varying by distance. Keep the game as long as you want with no late fees or due dates. When you're done with your game, drop it in the mailbix, and GameFly will send the next game from your GameQ.
