Cod 4 is like the popular persons videogame, its kinda following the footsteps of halo.
In the americas, if you want to fit in with all the bros and cool people, you need to play cod 4. That being said, COD4 could be a much much worse game and still sell just as well. (Thankfully, it is a very good game.)
Still, the quote "Boiii lets go knock a few back and play xbox live boiii" I hear that a lot at university. and its usually associated with halo or cod 4, with cod 4 coming out on top. Also, if you're a young teenage boy, if you dont play call of duty you dont fit in at school.
