For $60 there is tons of content and replay value, and that's not even considering that it is the biggest franchise in gaming right now. In terms of sheer content, the cod games are loaded. Sure this is meaningless for those who dislike the core game, buy you can't deny how much game you are getting with each release. Lets all just face it, the single player campaign of the COD games is very fun. I know the campaign is a rip off length wise and there really is no challenge. but what can I say? It's still FUN. Call of Duty is a juggernaut, and that is why it's great.
