This is my first post here, and I am joining the swelling ranks of the JK2 fanatics. If only there weren't more hours in the day...
I just wanted to throw my insignificant weight behind some of the requests that have already been expressed. Here are the mods that I would like to see (basically the ones I used in JK):
Ep1 Obi-Robe Kenobi
Hell, any Ep1 or 2 jedi
Blastech DL-44 to replace the Bryar
Hoth Echo base
Forest of Endor
But, let's be honest, I'd be happy with just about any mod. That's what makes the JK series so great.
