What is the most popular video game ever

Most popular? Well, this question will most likely result in debate. But according to the IGN, gamerankings.com, Game Informer magazine, and the fact that I am related to Chuck Norris (long story) i'd say the best games are (by series, not specific game):

5) Pokemon

4) Super Mario Bros.

3) Halo

2) Call of Duty

1) Legend of Zelda

I do not completely agree with this list. Mario should go last and Pokemon take it's place. And Fallout should kick out Halo. But other than that, it looks fine to me. :)
