I believe that might be for games you access via the website. My situation is more for when you have the whole game downloaded offline and want to set it up.

Thanks! So I would just set up Wine according to this, configure the prefixes and then run the game?

On another note, It just hit me that Proton was Valve’s version of wine (from my understanding). I’ll definitely give this a shot. Thanks moonpie!

Thanks for sharing. I do something similar with the --delete option on an external drive in case I screw something up.
