They have Civilization VI on the list. I found that setting up a Civilization game on my steamdeck to be rather difficult and did not try to progress to the actual game due to already difficult setup.
I play Civ VI on a tablet sometimes and often have to play with my ApplePencil. I wonder if their numbers can differentiate between playing on steamdeck and playing on PC or simply group them together?
I think I will give Civ VI another try on my steamdeck to see if the actual gameplay is better than the setup.
Edit: Apparently roman numbers are hard. Its VI, not IV.
I just got the 64GB version, from what I read the storage is pretty easy to expand, and the SSD slot isn't too slow either.
At US$360 it's almost the price of a new Switch OLED, which if I'm able to use most of my steam library on, then it's a LOT better in my eyes than a Switch.
