Over the course of last couple months i have been asked to help get new players get going on Linux...
I usually point them to my installation video (somewhat boring I must admit):
thereafter I use a script to launch the game or server.
i keep it in ~/bin as it is in my $PATH, it has to have i't executable bit set for the intended user (i have all three "up")
$ chmod +x ~/bin/MWLLgame.sh
Hope you have good fun and share some screenshots and PC configs here
