>>58120 (OP)War thunder mobile is kinda gacha but not really, you just research the tanks. If you like military vehicles its worth a try, doebeit it is made by a spiritually jewish company. A lot less grindy than the pc game surprisingly.
Find a ROM of PVZ 1 and the kingdom rush games. They are good. The port of Stardew Valley on mobile is really good, just gets updates later, if you care about that type of game. It does cost money doe, so pirate it if you don't want to pay the ~£5.
Solar 2 is a good game if you find a rom.
Get an emulator and play gameboy / gameboy advance games, they work fine on mobile.
