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.
