In each Call of Duty, there is an extremely satisfying moment, in either singleplayer, multiplayer or even the coop mode. For me, there have been multidudes of these satisfyingly delicous moments.
My favourite moment in any Call of Duty is when I reached Prestige Master in BOII. Although it might be slightly cheesy, I spent nearly a whole bloody year leveling up, while huge distractions stood in the way, such as my PS3 breaking.
These distractions made the moment all the more satisfying.
Also, on an unrelated note, I believe The Dark Knight Rises to be the most satifying movie ever made. I don't no way, but I think I wouldn't have loved it so much if it wasn't so amazing safisfying.
