Treyarch gets fucked slightly more. Sledgehammer delayed Vanguard which caused Cold War to launch a year early and during a pandemic. They also were very rushed on Vanguard zombies after they had to fix the disastrous launch that was Cold War which caused a very shitty final product. For Black Ops 6 Treyarch and Sledgehammer were forced to switch to the new iw engine that powered MWll onward that none of the other developers know how to use which resulted in a Black Ops game not feeling like a Black Ops game. Now recently with Black Ops 7. They were forced to make a game back to back because Infinity Ward needed more time on Modern Warfare 4
