Really excited cause I got it somewhat working. mouse still sucks but here we go...
besides the missing sergoeui font other already reported (if this one is missing the game crashes) it seems that other fonts are also missing.
to resolve the issue i checked W10 standard fonts: https://learn.microsoft.com/en-us/typography/fonts/windows_10_font_list
Extracted all TTF i get (bash):
fonts="arial.ttf ... wingding.ttf" # shortened list
cd ~/.steam/debian-installation/steamapps/compatdata/593030/pfx/drive_c/windows/Fonts
ttf="REPLACETHIS" # check the Fonts dir and chose one, i.e. micross.ttf
for f in $fonts; do [ -f $f ] || ln -s "$ttf" $f; done
videos do not work

crashes while moving units.. seems like a overlay cannot be shown

Waiting the next game hang and knowing that perhaps I miss some informations because they don't showup is a no go for me.
missing text or wrong text size
Randomly (but often) hangs after coming back and forth in game on one monitor and desktop on other monitor. Fullscreen is unuable for me because it disable use of the second moonitor. I can't play this kind of game without another monitor for rules, notekeeping...
"Workig at a 95% level" is not enough for me to be playable.
You can basically play a game as long as you aren't min-maxing every move. Wouldn't recommend playthrough in high difficulties.
- No visible text on the map (POI names, supply values) even after manually installing all SegoeUI fonts
- Screen flickers when opening/closing menus
- Does not stay in fullscreen mode (could be a tiling WM problem, though -- i3)
Does not stay in fullscreen mode -- maybe problem with tiling WMs (using i3)
Zooming is not smooth
No visible text for POI and supply on the map

Unable to use sliders in menus, game simply doesn't react on them
