Hello all,
Hello @Jason Carr	
I think it can be handled with the command line :
-p, --path=PATH          Path to where the game is installed
--savepath=PATH          Path to where saved games are stored
--extrapath=PATH         Extra path to additional game data
Additionally, you can maybe add a dropdown menu to choose the desired game language: 
-q, --language=LANG      Select language (en,de,fr,it,pt,es,jp,zh,kr,se,gb,hb,ru,cz)
