The new update switched the way that the mature content filter works. Previously, it defaulted to "show mature games" by default. Now, you have to check a box to show those games. That said, looking at it right now it looks like around 30% of games have self-identified as mature content. We intended that flag to really be used for "really mature" games, not just games with things like a little strong language...so I think we need to either switch it back and come up with a different plan or get the word out about that change better and more clearly define what we're thinking of when we say "mature game." At any rate, short-term, be sure to use that option to show those mature listings if you think you aren't seeing listings you were seeing before.
