You see, it is partly Google’s fault for allowing the sideloading of apps.
Google play just isn’t as profitable as the App Store, so a lot of dev’s aren’t bothering to port their apps to Android.
One of the reasons I recently switched back to the iPhone is because the App Store, in my opinion, is much better.
Just to clarify (‘cause I don’t want to start an Android v iPhone discussion) I was on Android for two years and wanted Google Play (or the market) to succeed.
So I did play Fly, Dragon, Fly due to the lack of any alternatives.
