The top 100 was more useful a few years ago, before the onslaught of new owners ranked their new games perfect 10's.
But the current rankings make the game owners feel good. Pin businesses like it too. So really, the only downside is corrupt data.
And for anyone who really cares (me/us), we know better. So whatever, it doesn't matter. Buy buy buy.. it's top 15 on pinside with only 13 plays!
