I think most would disagree with me but my idea of “old school” minecraft is before the biome and terrain overhaul of 1.7

Considering the fact that you’re using a touchscreen device which isn’t great for things like platforming or action RPGs, I recommend checking out more turn-based RPGs. The Final Fantasy 4,5,&6 ports on the GBA are fun and look great, as are the first two Golden Sun games. If you get your hands on a good DS emulator I also recommend Dragon Quests 4-6 on that platform
