I will admit... I am a COD4 addict.
It is the holiday season for me, I normally have very little leisure time. If I do play it is late at night (9:30 - 12:00 EST). I have been playing COD4 between those time frames... our server is normally empty at those times and due to the small amount of time I have, I want to play immediately.
Soon the holiday vacation will be here and I will have much more time free.
