Waydroid works, but there's three main things you need to get things going to replicate a typical Android device:
- OpenGapps: For GApps/Play Store. You'll also need to register your device to get an Android ID.
- Magisk: Mainly to pass SafetyNet / Play Integrity basic checks.
- libndk / libhoudini: For ARM > x86 translation. libndk works better on AMD.
- Widevine: (optional) L3 DRM for things that need it, eg Netflix
There are some automated scripts that can set this all up. I used this one in the past with some success.
Also, stay away from nVidia. From what I recall, it just doesn't work, or there are other issues like crashes. But if you're serious about Linux in general, then ditching nVidia is generally a good idea.
Finally, games that use anti-cheat can be a hit-or-miss (like Genshin Impact, which crashed when I last tried it). But that's something that you may face on any emulator, I mean, any decent anti-cheat system would detect the usage of emulators.
