Proton: 5.0-9 (I apologize for the disorganization. First report here, and upon writing this, I was only given the "Extra Notes" section to type in.) At first, the game would launch the launcher and show a grayed out play button, and following the recommendations of others, I used the launch option "/nolauncher" to disable that, along with the other instructions listed by matiasgr. Tried launching the game again - before the loading screen, I'm prompted with a message about my page file being too small. (I've had this problem before with certain other programs run through wine, but it's never been a problem.) Bypassed the launcher just fine, and made it to the loading screen. After 15 seconds or so, however, my screen would go black and the only way to exit the game and do anything else on the computer would be to completely restart the computer. Would have to do this physically rather than digitally, since everything is locked up.

Eventually found someone who mentioned installing vcrun2017 via protontricks. Did this - the game made it passed the loading screen to the introduction cut scene. Did not make it passed that, though, and locked up my computer the same way as before.

May very well have something to do with that page file warning, but I've had no luck with figuring out how to fix that.
