I love the CoD series. Can't wait for Modern Warfare 2. It's gonna be off the chainnn!
I only have CoD4 for the PC now. I used to have it for the 360 but I traded it in... though I kind of regret that decision cause I've been really thinking about playing it again. I liked it on the 360 when just playing multilayer more (I played it on PC very competitively and went CAL-IM with it - but have since stopped).
