I have it for both
But my friends don't have it for the PC so I got it for the 360 and adapted to it...I'm a lot better on the 360 than the PC though...the keyboard cramps my hand if I play it too long...which I do :P
train yourself then >_>
English language ftw! Native speakers ftl!
CoD is better played on pc imo.
Have you seen Retaliation? CoD4 machinima, made on PC. It's absolutely kickass! Course, it could only have been done with PC, seeing as there's a FRAPS usage overdose.
