Great, and could use some additions.
4 stars because there is room for improvement; such as allowing users to modify the remaining list to have only games you care about - or having variants for cart colors. Thats important for a few games. Also, pics of your own individual carts/boxes/manuals would be the next step. App works quite well otherwise.
