As we all know, there are three companies that are working at Call of Duty. Treyarch, who made the Black Ops series and World at War, Infinity Ward and SledgeHammer who worked on the Modern Warfare series and then Ghosts and Advanced Warfare. So between the three of them, who has the best capabilities of making the best possible Call of Duty game. In my opinion, I really enjoyed Black Ops and Black Ops 2. I found that Black Ops had the better campaign in recent years in the Call of Duty franchise. So, I favor Treyarch. What about you guys? I find it that it may be a bit biased that I post this in a Black Ops 2 Discussion Area, but I am not at all tipping any decisions into Treyarch's favor.
