So that title is just a straight up lie. They want to use a de-googled Android.
To be honest I was hoping for an alternative OS, competition is always good. But a de-googled Android could possibly be good, but being Chinese I assume instead of Google telemetry you'll just be replacing it with CCP telemetry.
An old style game would be perfect for mobile. Not too graphically intensive so battery won't drain as fast as Pokémon Go and should run on even budget phones.
They could then keep the 3D games for consoles.
