Gamesir X5 Lite – what to play?

Very proud of my setup; nonetheless, I'm new to Android gaming and questioning what to play.

Straightforward-to-set-up emulators aren’t too heavy on controllers (GBA, SNES, and many others.).

I attempted COD Cell and comparable video games, however they didn't work with the Gamesir.

What free video games do you counsel? I'm a CS fan and used to play video games like COD, Battlefield, and Starfield on console.

Thanks!
