Wow..
Sorry just thinking how you can play Civ 6 on a mobile!
I need a full desk, mouse, big screen and coffee machine next to me for Civ sessions
First game I played on my deck was civ 6
It's actually perfect for it - when you have 5 mins, turn it on, play a couple of turns, turn off
Not sure how well it would work on pure touchscreen, but if you had a controller for the phone then I can imagine it would work pretty well
