Also while we’re at it, The World Ends With You is built for touchscreens, and is one of the best RPGs in the world. It’s input-heavy, but it’s not trying to mimic a controller. TWEWY came out on the DS back in like ‘08 or so, and eventually got a Switch/ios/android remake that changes and enhances a lot of stuff.

It’s also a kickass game that celebrates Shibuya’s culture, which is an incredibly refreshing setting even twenty years later.

Honestly, Civilization VI is the heaviest game on my phone. Touch screen is beautiful for it too!

See this past comment and the whole thread. The topic of Android games is brought up repeatedly here.

If you have a tablet, that's a whole another world: I've played OpenTTD and a port of ‘Master of Orion’ on mine. You can also run a whole bunch of DOS games with Magic Dosbox, or graphic adventures with ScummVM.
