I have a laptop (the HP Zbook Studio G4 (I know, that is not really a gaming PC, but it is quite powerful)).
On my phone, I mostly played Asphalt 8. It is a racing game that is in some way realistic (real cars, real locations, handling is a bit like in real life), but mostly it is an arcade racer. You can use nitro to go really fast, you can drift around every corner and barely lose any speed, you can knock down others to pass them, and most importantly you can fly hundreds of meters if you drive over a ramp.
