I have Witcher 3 installed trough wine.
I use Gnome
It's in custom prefix
Now every time I want to play I need (probably not, but I don't know the different way) to repeat steps in terminal:
export WINEARCH=win64
export WINEPREFIX=~/Games/W3
wine ~/patch to Witcher executable

You write a shell script or a desktop service? (You can use "env" in the latter to set the environment variables and run wine)
