I've had the same opinion for a long time that CoD is a fast-paced arcade shooter where reflexes and aim matter the most designed for more chaotic action, something many other games such as Battlefield aren't. They're incomparable.

Although I'm not exactly sure if any of the common FPS features come from CoD (particularly the "some of the weapons" bit; they exist in real life, that's usually the inspiration for having them in a game).
