AM2R a.k.a. Another Metroid 2 RemakeIt’s a fan game of the 2nd Metroid game, and is considered one of the best of the series, even though it’s not an official release. It’s more like Super Metroid than the Gameboy title is. You’ll have to search around a bit due to Nintendo’s D&C, but it’s not hard to find (the internet archive has recent versions).
MinecraftIt’s a good port, but probably best played with a gamepad &| tablet.
Portal KnightsA minecraft-like voxel game with more satisfying progression and combat, but less creative freedom. Plays well on newish devices, epsecially with lower-quality settings.
TerrariaIt’s a great game all-around, but harder to play on mobile than PC.
EmulationThis goes without saying if you like retro gaming. The best emulators I’ve found are the .emu apps by Robert Broglia. They can be bought from the play store, or obtained for free at his Github page. If you like original Playstation games, get the Duckstation emulator (produced by another dev.).
