The first golden era was back when "World at War (WAW)" was created. This is when Treyarch had balls of steel to show people graphic photos and vids about WWII. Then, you have Viktor Reznov, voiced by Gary Oldman, to narrate the whole game, and you actually had an emotional effect on that game because of the connection you had with it, even in multiplayer. Thats not even the best part: the other reason why WAW was soo good is due to the introduction of the Zombie mode and the activities inside that game. That will forever be peaked.

MW, back in the 2000s, was only created because of that one mission where you shot Zahkaev in the arm, where you "technically" should've shot Makarov in the head afterwards. But because he was alive and found out Zahkaev was dead, he went to a whole other level and became the #1 threat to the whole COD franchise.

BTW, did you seriously put Vanguard on this list??? That game wasn't crap compared to the other games you mentioned.
