These two video games were released around the same time of the year and both of them had immense hype and build up prior to their releases.
There have been quite a few discussions on internet forums and other platforms such as social networking sites where fans have been divided as to which game is better among the two.
By playing the two games side by side, one has the feeling that Battlefield 3 has a certain amount realism to it, which is not there to be found in Modern Warfare 3.
