Anyway, I’d pick Modern Warfare. On average this is the best sub-series, with great campaigns, multiplayer, and co-op options. After MW3, everything kind of fell apart. Infinity Ward turned in one great campaign in Infinite Warfare, and Treyarch developed some good multiplayer modes, but it’s been a generation since CoD delivered the goods on all fronts.
WWII is second for me.
