A large number of apps require Google Services be installed and won't work with bare AOSP anymore. Location services is part of Google Services now, so apps that require it need GS. Every app with in-app purchasing won't work without Google services, so you can forget about most games working on AOSP. There isn't one Android anymore. There's the base pure open source Android, aka AOSP. There's Android with Google services, which supports things like the Play Store, in-app purchases, location services, etc. There's Amazon's Android fork which has some of their own APIs inserted for in-app purchases and location, but Play Store, Google Chrome, Firefox, etc are unavailable for it. Now there's Nokia's new Android fork which will have its own set of APIs for location, in-app purchases, etc.
