Has anybody tried to run Arctico on Linux under Wine? Any luck? Appdb.winehq.org has nothing about it.

It works fine for me. I'm using Proton 5.0-9 with no unusual configurations. I can't remember why I chose a rather old version of Proton over a more recent version of Wine - maybe it worked easily with Proton but could have required a little tinkering otherwise. I'm using adamhm's generic Wine wrapper (which can be found elsewhere in these forums - I don't have a link handy right now) since I don't like to use launchers. If you don't want to go that route, Lutris or Playonlinux might be the easiest way to install it.
