The single player is awesome, all killer no filler and that.
I loathe real war settings thinking them untasteful and needless, but CoD4's excellence won me over. So many stand out moments...

The rescue the chopper pilot before the nuke goes off story was excellent. Ho hum I thought, another Americans save the day never leave a man behind story. And then the nuke goes off. Then the "level" after that? Fucking awesome. The nerd in me thinks it is quite a powerful example of what video games can manage that cinema can't.
The Grainy IR footage from the plane as you kill people whilst the radio chatters was horribly realistic.
The whole of Captain Price's flashback was a theatre of excellence.
Overall I'm surprised how much I bonded with my fake SAS squad as well. Especially good old Captain Price.
Incidentally I've just worked out that this guy from eastenders was Price.
That was bugging me a lot.
