I woudn't say the simplified it. On the contrary, compared to CoD 4 they have added a lot more additions, to weapons, perks, killstreaks, etc. But I agree that CoD has always had such a success because it's a casual game that everyone can pick up and be good at. If they probably changed that formula many woudn't buy it.
