The reason why I use this site is because it is acessible on my Android phone, is there a way to have a list that shows the games you don't have. What I mean is if you have 500 or 600 Nintendo games, it would be nicer and easier to be able to pull up a list of the games you don't have. Can this app take the games you do have, subtract them from the games database, and give you the games you are missing???
