Recently I bought Big Pharma and ran into issues running it on Linux Mint. Using the default Open Source Drivers for my system causes the game to not render graphics properly and makes navigating the menus difficult as clicking on the buttons does not always work. I was able to play through the first tutorial, but the graphics were not working.
To fix the graphical problem I upgraded to the proprietary drivers on my system, which first lead to the game not loading past the developer logos with the Steam Overlay enabled. Disabling the Steam Overlay allowed the game to load but it then would crash if you entered the ingredients tab(likely other tabs as well but I did not test further). Graphically the game worked and the menu buttons were no longer an issue, but crashing makes the game unplayable.
I have tested this on both the Steam Version, and the DRM Free Standalone. I believe the second issue is related to Unity3D not working properly with the proprietary drivers(unable to play Table Top Simulator either and saw it had logs in the Unity3D folder just like Big Pharma).

Note: I had to boot up a live usb to take the open source Ati screenshots as I was unable to switch to them on my laptop.
