I came across this one on HN a while ago, and have found the recommendations to be quite good: https://play.google.com/store/apps/details?id=com.curated.an...

I wish Valve would expand Steam into the mobile gaming market. That would certainly help with the discovery problem, with frequent sales, user reviews, custom tags, and whatnot. Also in my experience, their recommendation engine actually works pretty well.

Obviously they'd have an uphill battle on their hands, as they can't distribute their store app on the Play Store, but the Amazon App Store seems to be doing decent so far despite that handicap.
