The only game i got to 10th legit was WaW before all the mods came out.

I think the best call of duty made would have to be Black ops 1 Everyone hated it but I found it so much fun!

Modern warfare and modern warfare 2 were my favourites

I will have to say cod4 most people say mw2 and bo2 because most of them haven't actually played the older games in there prime without all the modders. Some people may have liked the game I understand that, but overall COD4 had to be my favorite, after all it was the only COD to get game of the year.

Campaign wise I actually loved Ghosts, it was different and actually appealed more to me since you mostly had small grouped missions and not some giant scale battle like they did in the Modern Warfare games.

Multiplayer wise I enjoyed World at War (before all the modders) because it was without a shadow of a doubt the most gory since you could actually shoot off limbs.

By far Modern Warfare 2 is the best call of duty ever made, and in my opinion, the best game ever made. Will always be my favorite.
