I’ll start with GTA: Chinatown Wars and Animal Crossing: New Leaf.
Let me know your suggestions!
Pokemon Red & Blue are amazing to emulate. Old but gold.
There are many Pokemon ROM hacks that you could play as well. Renegade Platinum is my all time fav
I think most turn based RPGs play great on touch devices. If you don’t have a controller, it’s fine because fine-tuned controls usually aren’t that necessary. They’re also usually meant to be picked up and set down, meaning you can grind a few levels while you’re just chilling on your phone or something.
2D games that don’t use L/R buttons are very playable without a controller.
Older systems that didn’t have L/R buttons in their controllers seem to work well
Anything from NES, Sega Master System, Sega Genesis/Mega Drive, Gameboy/Gameboy Color and Turbo Grafx 16 tends to work well.
i’d suggest any touch only ds games. ace attorney is particularly good.
