I viscerally crave Deus Ex: Invisible War. It's almost physical. My breathing becomes shallow when I read about it. I become pale and perspire. If there were more Thief 3 info available, I might have a similar, if not more extreme, reaction to that, but for now I can do little more than read Warren Spector talking about open-ended game play and different factions and all the possibilities they've tried to encode through player-defined game paths and wait.
December, they say. December.
December, they say. December.
