gamers especially the most hardcore of the hardcore are pretty fickle and fiercely defensive of whatever they like to the point of not making sense and disproving their own points with their arguments. One of the most used argument is that COD hasn't innovated much. Usually the person that makes that argument is someone who loves BF. I have played at least the last 4 BF's and while I do like the games, they haven't innovated either. The only one that can really complain about innovation is the gamer that is switching from one series to the other. Anyone that has played the last 3 versions either series is probably only using innovation as an argument because they heard it in another thread. Cod has the largest sales numbers ever and honestly a very large portion of those fans have never been on a internet forum or ever will. Bf on the other hand is more of a core gamer/computer nerd thing and as such you will constantly see them crying on boards about how COD sucks even though critics give both games similar scores. Oh and to call BF realistic is a joke, try a game like ARMA or red orchestra and you'll be begging for some COD afterwards.
