They are Billions

What works

Launching the game works, HOWEVER a (somewhat lengthy) workaround is required. Specifically, this WineHQ Forum post describes the whole ordeal required to successfully launch this game.

I can confirm that the steps described in there worked for me, though I had to forcibly restart wine by killing the process at a certain point, since the .NET slim installation step got stuck. After that the game ran successfully.

What does not

A major problem is that some text doesn't replace but overlaps the previous one, so some menus (like the new game menu) become illegible if options are changed more than once. This is solved by exiting and re-entering the menu. Unfortunately for other parts of the game, like the in-game on-hover tooltips there is no way to fix it without restarting the game... So it quickly grows from an annoyance to something that makes the game unplayable. Especially if you are new to the game and don't know all the buttons by heart. 

The game also sometimes randomly crashes when starting a new game, and in the main menu, though not when gameplay is actually happening, as far as I can tell.

Furthermore, when the game self-restarts it fails to actually start anew, and so it crashes after it exits.

Workarounds

The lengthy workaround is as reported in this WineHQ Forum post.

Note that this only makes the game launch and reach the main menu, it does not solve the already mentioned overlapping text that makes the game unplayable.

What was not tested

Anything past the first few minutes of gameplay due to the game becoming unplayable with overlapping text.

Hardware tested

Graphics:

• GPU: Nvidia
• Driver: proprietary

Additional Comments

Again, the workaround process was weird and I almost gave up after I didn't notice that the slim installation got stuck in the background even though it had exited successfully. It was only after a complete termination of the wine process that the game successfully started working.

Despite what the forum post says, the game manages to start both with a wine virtual desktop and without it.

Tested both with the Nvidia graphics card (& optirun) and with the integrated Intel graphics card.
