Jason Paglow proposed sorting games by multiplayer/single player.
How about also tagging the games with information you already collected anyways in your database? Will Stackable said, you guys developed a scorecard to help you curate games. You give them scores based on use of grip buttons / violence / ease of menu use / etc. We operators would love to have that information without trying out the game ourselves too!
It is really time consuming to download and try out games only to find out that you will need grip buttons. So it has real value if you already have that information at one glance. Best example was super hot (the home version at least) which required you to learn the trigger plus grip buttons on both controllers in order to do the mind attack. But only once you were half through the game!!
