"FPS.... too bloody and fast-paced, RTS?... too complicated(though he does play C&C3 from time to time, not that he's good at it) RPG?.... well.... what then?" and then it occured to me,
there aren't much RPG games you can play through lan, the only ones i know are
Secrets of Ultimate Legendary Fantasy, UNLEASHED! which is free but too short, and only fun the first... 10-20 minuets you play it( and it's open source too

So I have few suggestions
A. Make it a community project to make "Elysian Shadows" Networkable/dual characterable (Woof!)
B. List LAN RPGs you know here.
C. because it comes after B...

Edit:
Tried Diablo but bro didnt like
