But 2 was packed full of combat! And the original had a cardboard protagonist too!

The demo featured the least interesting part of the game. There's pretty much nothing of note in the demo. Piloting a giant mech through the wastelands, battling through a gradually crumbling aerial fortress, or running through a factory wielding a gun that shoots fucking lightning were far more interesting.
And it had a METAL SOUNDTRACK, in a ARAB SETTING with an ARAB CHARACTER. Next time you'll know that COD will feature a inspired song by Morning Musume.

I'm now seriously thinking about striking my friend in a head with a heavy object and snatch the PS3 from him for a bit.
