It’s a seriously complicated UI but once you get used to it it’s pretty fun. The use of the default non-android keyboard will take a while to learn all of the key board shortcuts.
Also note that you don’t actually need to manually use arrow keys at all. You can use ‘o’ to auto search the map and Tab to auto advance to / attack enemies. You can also zoom in a bit with volume keys to make the map a little more visible
Ita not a single game, but I waste a lot of time on gamesnacks.com
Yeah I got the steam deck in the early spring this year and am still trying to get through Witcher 3 and fallout 4. I have a handful of games I got for PC back 15 years ago on steam that I still need to work on after that
