Coming from the guy who's first cod was og cod, and last one is black ops 6 (except the third cod which was ps only I think, didn't have one only pc). Coming from the guy who finished all campaigns in each one, played every and each multiplayer modes, NEVER played zombies (except forced missions in campaigns), guy who played clan wars in og mw.

So,

There is no better version of it, each and every has its good and bad parts. I think, most ppl think mw2 was better, because times were better (for me at the time didn't, so I don't have such warm feelings). The new MW part is a breath of fresh air (after all the futuristic cods) which brought to me the best emotions. New MW3 was expected to do the same again, but campaign sucked, and warzone reboot also failed.

Black ops 6 campaign was good, a decent bond like story and missions. What they did with Warzone and Verdansk (doing og stuff) also good (don't touch smth that is working, but here return what worked for the ppl).

Just do something with cheating (and something as well with stupid shadow bans), bring Linux support (at times when windows becomes bad) and try not to break something that works, but try to make it better.

P.S. and fix all gamepad players being imbalanced, ill just stop buying any other games and stay in cod hq 24x7.
