What is your favorite Call of Duty game?

[OdinHades]

The very first one, I especially enjoyed the Addon United Offensive a lot.

I really miss the option to set the bodycount to insane in modern CoD titles, btw. I loved it when every single enemy you killed stayed in the level forever. Sure, you needed a lot of RAM for that, but what the hell, just give me the option, ok? =P
