Call of Duty has been around for a lot of years. This franchise boomed when call of duty 4 modern warfare was released then followed by a bunch of other call of duty games made from different companies.
Activision made call of duty 4 and modern warfare 2 while Treyarch made world at war and black ops.
I think that Activision did a much better job then Treyarch at making war games like call of duty. The online is much better on call of duty 4 and modern warfare 2 which happen to be made by Activision. The graphic are also much better on the games made my Activison. Everything about it is better then what Treyarch produced.
