Did multiplayer LAN work in Anno 1800 for you out of the box, or did you make adjustments? I couldn't figure out how to get it to work.
StarCraft 2 worked, oddly enough, run from Steam as an external program. (Lots of search results tried to get me to use Lutris/bottles, but I couldn't get it to work consistently under Lutris.)
I’ve done multiplayer internet play rather than LAN play, but that worked just fine without any changes from my part.
In Lutris it'll try to run on Wine 8 by default, I had to set it to use the latest Proton GE.
Was also able to get WoW, Diablo 4, WC3 and SC1 running well this way, since they're all in a single Wine Battle.net install.
