I have enjoyed the 2 new Modern Warfares -- I played Cod-MW3 growing up, but only the campaigns, so MW2019 was my first MP COD, and I had a lot of fun for what it was. Warzone was also the first BR that appealed to me, and I ended up playing a lot of it as well. I'd guess I completed 3-4 battlepasses before I realized I wasn't enjoying myself anymore
I skipped BO3 and Vanguard, but by the time MW2 was coming out last year, I had the apetite to try CoD again, and the campaign was okay (not as good as MW2), and I enjoyed the MP about 2/3s as much as I did MW2019. I had some fun with the extraction game mode, and finished the S1 battlepass, but haven't come back since.
Another MW3 so soon feels like a misstep here. I am curious about the campaign, since it seems like they're mixing some cool setpiece levels from MW2+3, but that's not worth full price to me.
