If you have PS Plus, Cold War is one of the free games this month. While some people prefer the more classic style, definitely don’t sleep on this one. As a bonus, all the dlc content is free in the post-bo4 games.
Black ops 3 is also a great choice, just look into the dlc options before purchasing (it’s all good, just deciding on a bundle will save some money). The PC version also benefits from steam workshop support, there’s a lot of great original maps and even remakes of some classic ones.
