Yes, I’ve used all my apps pretty seamlessly. I had to turn on “exploit protection compatibility mode” for some of them like banking, but they work fine. You can get Google Play, and it runs in a sandbox, but I use Obtainium and Aurora Store (Aurora in particular would be of interest to you, it’s just a frontend for the Google Play store which allows anonymous connections: https://f-droid.org/packages/com.aurora.store/). I moved to Aegis for my 2FA because I was looking for a way out of the Twilio/Authy ecosystem. I don’t play games on my phone, so I can’t report back on how those work.
