For those who don't already have it (like me!), there's a special going on at Amazon where if you buy Modern Warfare 2, you can get another Call of Duty game for free. I got Modern Warfare GOTY as my free game, because i've been wanting it for a long time. I just wanted to inform people of this. Ended up being $53 for both. I wouldn't have bought Modern Warfare 2 for $53, so this deal was good for me because MW2 is worth $25 to me.

Cool, thanks for the share.

Shit, that's a good deal. 
 
MW1 and MW2 had good campaigns, so this is really well worth the money even if you don't play multiplayer. World at War is worth a consider if you like Nazi Zombies though.
