As a Call of Duty game, I enjoy it. The guns feel good, the characters are very interesting, (though it feels weird that you only play as good guys? So in multiplayer your idk just going on a killing spree??)
I know some people don't like the maps, due to the remake of some World at War maps. Personally I find this a huge suprise, I don't watch trailers as to not get over excited, so seeing these maps from my cod childhood was really really exciting!
Is it bare bones? A bit yes.
Are all cod games bare bones on release? YESSSSS
Tldr; buy it if your a fan of CoD, cuz we both know as the seasons roll in, loads of free content is pumped into the game.
If your not a cod fan, Id say wait a few months for it to flesh itself out, then maybe dip your toes into it? Or buy cold war to see how cod games can end up after 6 seasons of content!
