How to install a game with Lutris on Linux PC without the use of a pre-made install script

Demo how to basically install any game with Lutris on Linux PC nowadays. Missing voice over, couldn't bring myself to do any so far but it's really just a matter of clicking "Forward" and scramble for a mug of coffee/tea while waiting for the installer to finish. I had no idea if this would even succeed so you see me fumbling around in the menu of the game later and even switching to DX12 (while I was just looking to disable that gorram motion blur that really NOBODY likes!) Nice game tho. Can recommend :)
