Seems like the best you could do at the moment, except maybe the 3DS if it has some new feature, is to compose a games list displaying people's collection and whether they beat the game. Create some kind of point system from that and people can see how they match up. All done by the honor system though.
Or you could wait to see if the Wii U will implement a system then you will have a fresh start on comparing gamers starting with early adopters.
Before the PS3 everyone was nice to me :(
