I've already seen some pretty cool star wars mods, but what I'd really like to see is a Co-Op single player mod.. I was hoping this sort of thing would be in game, I'd love to be able to play with my girlfriend instead of both of us playing seperatly, I end up spoiling things for her... Anyway I was just interested in what you guys were looking forward too.
Edit forgot to post the link the Star Wars mod...
