I bought every Call of Duty from Modern Warfare on and I really liked the series as well. The last one I truly enjoyed was Ghosts. There was a fun campaign and multiplayer, but the real fun for my wife and myself was in the extinction mode. It was what I had been looking for everytime I played a game of zombies, a horde mode of sorts that can be beaten. All the while the futuristic aspects weren't insane like newer games. Once the COD franchise started introducing exo suits and robots I lost all interest in playing the campaigns. I wanted to play COD for relative realism and I would play Halo for futuristic aspects. I only played half of each game I bought after that. I always knew the games were a money grab releasing one every year, but at this point I decided unless something changed I wouldn't buy anymore. My wife did buy me Infinite Warfare last Christmas which I installed only to play the remastered version of Modern Warfare 2 and then delete Infinite Warfare after I realized I didn't need it to play Modern Warfare 2. I may rent WW2 someday, but for now I am done with the series. I hope you continue to have fun with them.
