The intensity of this game reminds me of the good old days of World War II Online, sitting in a bunker manning a gun, in the pitch black staring at the door way, afraid to blink. Listening to the panzers moving in....the screaming and dying getting closer. Knowing that soon they would rush the door I was guarding, and if they got through the city would be lost, and it could take days to get it back, if ever. I got hooked on that game pretty bad, back then. I'm pretty hooked on DayZ now. Exactly my kind of crack.
