Just do what I do. Buy the games when they are on sale because it saves you money. Then add the games to a folder called "Waiting Queue". When your done with your current game, go to the folder and pull out a new one to play.

Then you will keep seeing yourself coming back to the same game over and over despite there is many other on queue because some game are just that good.

Now excuse me, I need to play Minish's Cap for the 7 times.
