Nintendo is Right, But They Don't Get It Either
From HDWarriors.com

Call of Duty 4: Modern Warfare is one of the most popular games released this generation, and was released on both the PS3 and the Xbox 360. On both consoles, it is still played by millions online, and with local multiplayer. Even allotting for the fact that every First Person Shooter developer to date so far (Including High Voltage Software with their upcoming The Conduit) has avoided split screen multiplayer on the Wii like the plague, (and a Wii version likely wouldn't have had it), the biggest reason why this game wouldn't have been nearly as popular on the console as the others is the fact that Nintendo's online policy hurts developers by lessening the appeal of certain games to the target audience.
