Nvidia's TegraZone app is primarily aimed at Tegra-powered devices, but the new update to version 2.9 opens it up to everyone. You can check out Nvidia's curated game listings if you're using a Snapdragon, Exynos, or whatever else. Keep in mind, not all the games you find will be compatible, but it can be a nice way to explore some good games

The app's UI has been tweaked to add better filter controls in the games tab. You can also restrict your lists to only show games with controller support, which is a handy feature for Shield owners. The Google Play Games stuff is weird – it actually gives you achievements for leaving reviews and downloading games. I don't know if that's how achievements are traditionally supposed to be used.
