I'm going on a trip soon and trying to get myself some things to do. What Android games should I play? Obviously not some cash grab games but something proper. My most played games are Kerbal Space Program, Minecraft, Stormworks, Red dead Redemption 2, Forza Horizon 5, Farming Simulator 19 and 22 and BeamNG. I'm thinking of Pokemon Fire Red on some emulator. Other suggestions?
If you've got the cash I think the Steam Deck is still discounted. With that you could play all the games you listed.
If not, Shattered Pixel Dungeon is awesome. And people seem to like Mindustry. I haven't tried the latter yet. You can find lots of games without any bullshit on F-Droid.
Since you mentioned Minecraft and farming simulator, both Terraria and Stardew Valley are on android, though I can't speak for their quality or playability.
Emulators are a pretty good shout, PPSSPP was pretty great when I last used it which was a few years ago now, so I imagine possibly better now and the PSP had a decent selection of games.
You could also try Google Play Pass for a month and look at a few paid games and see if anything tickles your fancy there, but subscription service.
