From the article, "If you search around the web, you’ll find websites writing articles about the games that have been updated to support Google Play games services. That right there is a problem. Google should have made sure there was an easy way for everyone to find these newly updated games. There should have been a dedicated section in Google Play for this very purpose. I feel that the majority of people won’t even know Google Play games services exists. And why should they? It’s a series of APIs that they’ll never see. Google should have released a separate app called Google Games (or something similar) that would face the player and help build awareness."
