There are a few good ones, all PC game ports, but for the most part, the only way to play good games on mobile is through emulators. I have a Steam Deck, so I don't do that on phones or tablets for the most part, but I do like using ScummVM for old point & click adventures on mobile, it's even avail...

I have an old portable Nintendo 3DS console with custom firmware. It's quite mobile and has a ton of great games. I recommend it.

Play homegrown and earn some sats!

This really depends on what type of games you enjoy! Because there are well built games in some genres. I like Pokemon Unite. League of Legends is also well done.
