I have gone back to CoD2 (on the PC) for a bit before to the release of CoD3 for the 360 and i am playing it on Veteren...

Now it is admittedly 1 man army in style, but there is a lot of friendlies around to and playing on veteren, while you light kill a lot in the end, but my god does the game make you work hard for it!!!!

The Brothers in Arms series was good at emphasising team work over individual runs...
