Post something you'd like to see or try to hopefully have present at PAX. I'll edit this post as more suggestions are made.
Battlefield 2 (hopefully a demo of 2140 will be out by PAX as well)
Wolfenstein: Enemy Territory
Call of Duty 2
Dawn of War/Dawn of War Winter Assault
C&C Generals Zero Hour
Empire Earth 2
EDIT: Divided games up by genre, and added more. Also bumping because I want more suggestions, and hopefully give people a heads-up on what some of us are looking for. Also fixed the wrong headings.
