Never reviewed this. It's Call of Duty. Campaign was solid but I'm someone who always plays the story and somewhat enjoys them. I liked the dialogue choice mechanic. It still feels like there's not much of a challenge from a gameplay perspective and it's a little uninteresting. I think CoD needs to do a full 180° and try something different. More on that below.
Multiplayer in the first half of the year was lots of fun. I enjoy Treyarch's movement a bunch. Second half of the year camping, head glitchin, and all the regular CoD bullshit began. It'll only get worse now that Vanguard is out. Still will place top of the lobby 95% of the time.
Personally I think CoD need to bring something fully fresh to the series. Don't hate me for saying this but something like The Division, the latest Ghost Recon titles, and even probably Far Cry. Open world CoD where you have a guiding hand for the story but can do plenty of side or optional missions like Cold War tested the waters with and marked areas to jump into a multiplayer lobby (multiplayer is still accessible on it's own). Will this happen? No. CoD will remain CoD until numbers drop so low they have to rethink the formula because they certainly are not dropping the brand.

Edit 01 (11h, Game Pass): Joining up with friends online is horrendous. When connecting one of us either dropped or was unable to load in. I even had constant popups saying there was a network issue on mine end despite my internet being well more than stable. When we eventually loaded in the minimap is terrible a identifying where your friends are thus making you rely on the main map. This makes world traversal a nightmare and the only reliable means of playing with your friends is to do races which ultimately are unsatisfying.

Original (3/5):
TLDR: If you like Forza you'll like this.

Super early thoughts (4h, Game Pass) of someone who's slowly playing racing games again: It's fine. The visuals are stunning and the open world is fantastic. I love just driving around going anywhere and finding something pretty to look at. Having just come from playing Dirt 5 the cars feel super light comparatively. This is even more noticeable in the shared cars between the two games. I'm not a fan of this lighter feel but it's not game breaking and with a adjustment period should be a non issue. I am however not a fan of the strict checkpoints in races. I understand why they're there so maybe strict checkpoints isn't the right term but I'm just not a fan of them. This leaves me being frustrated not wanting to play the built races. Maybe I'll come around on this in my play sessions during the week before I clear it for space.
The community liveries are amazing and that's something I'll miss after leaving the game.
