Mobile games usually get a bad rep as they’re usually asset flips and/or MTX-ridden and/or ad-filled, etc., and I’m sure this is actually the case for most games on the app/play store. But are there any ones that are actually good, maybe just something to pass the time with?
I mean… not sure if it counts as mobile but the entire history of console gaming up to few years ago works on emulators, so that’s a VAST choice. Sure you might dislike 99.99% but if there is even 0.01% you enjoy, that’s hundreds of games if not more!

can’t forget about NetherSX2. It’s a little bit of a pain to set up but it gives you all the PS2 options.
