Hmm...
STALKER (Even if it's in "Shit, let's make it somewhat playable to get it out before 2007" state, as THQ is demanding)
Gears of War
Half-Life 2: Aftermath
To be honest, I'm too game-jaded at this point. I like sifting through the detritus of yesteryear and playing awesome games that are more than, oh, 2 years old.
