lots of paid apps use license verification. that needs google play services on the phone, and a logged in google account that has the license.
often its possible to patch out license verification. the lucky patcher app can do this automatically in some cases, but I don’t recommend it actually because even I’m not confident what is the real official download site of it. it has features for rooted phones, but it can do some things without that too, by just patching the app.
but if the game is multiplayer, chances are that the servers will attempt to verify with google that you have a license, so that may not be possible
If it is a pay once and you own it kind of thing and never requires internet access for anything, then you may be able to back IP the all and use it later. But most games have some online component that requires a periodic login to use. Same goes for a lot if software on desktops, though.
most games downloaded from boogle play don’t work without boogle play (and probably the account with which you bought them. They’re gone. :/
some games have alternative (email only or Nintendo) signIns that you can use to carry your data to a nonBoogle platform
So with, say, Minecraft; am i cooked?
Believe it or not but I bought Minecraft on play store years ago and refunded it for some reasons but to this day, I can still download it for free ¯\_(ツ)_/¯
You can check Fdroid (some paid apps like OSM+ are free there)
I do not think there is a way :/
