Why do so many people say it doesnt require 'skills'?
If it's the first time you've played it and you think you've done good, congratulations, you know and have experience with playing first person shooters, meaning you have some knowledge and/or skills of how CoD works (in regard to controls).
If you do completely horrible, as chamara suggested, congratulations, you are either new to FPS's or do not play them regularly or do lack in hand eye co-ordination.
There's your argument, CoD DOES require 'skill' in order to be consistenly good at the game, as with any other.
Also hi, school is a bummer, so increased inactivity is headed my way.
