I tried CoD4 the other day but it seems that my onboard graphics card isn't good enough to handle it (the regular one fired up to the moon a few months ago). Sooo... I got a bargain bin version of Cod4 for my PS3 and have played it a little over the past week.

My experience?
About the same as your first match, only it lasted for several matches until I got to grips with the controls.
