I want to play Android games on Ubuntu 18.04. Some games are linked to my Google account so I probably need to run the Play Games and Play Store.
Note that similar questions have been posted here before but those posts are quite old and the main answers no longer seems to apply to 18.04 and current state of tech.
There are (2) complete Android OS platforms that I've have good luck with:
I have only run these under a virtual environment (Virtualbox and QEMU), but they can be installed as a dual-boot. Android x86 is more mature than Prime OS.
Now, if you want to run Android apps natively, there is Anbox (https://anbox.io/). It's harder to setup, and does not support Google Play out-of-the-box, but it looks promising.
