At the moment, it is not entirely clear what criteria Google is using to choose which games it will feature on the new list, but a developer of one of the featured games offered his thoughts in a comment on Reddit.
“I don’t know of any particular requirements [to be featured], but I can tell you what our data was like before we were contacted,” said Tyler Coleman, a developer on “medieval tycoon RPG” Merchant. “We (Merchant) had over 100k downloads and averaged over a 4.0 rating. We also integrated the Leaderboards and Achievements through Google Play Game Services, which might have been a factor.”
While the current list of games on the Indie Corner is small, a curated indie game page could be incredibly helpful for both users and Android game developers.
