Modern Warfare usually is discussed as a major franchise for the Xbox 360 and PS3 and is subject for debate on the PC. By at least one measure, it's significant on the Wii too.
Those who follow our monthly tally of Wii playing time (the so-called "measure of pleasure," as I've dubbed it) know that the average amount of time that Wii gamers spend playing 2008 Call of Duty: World At War is sky-high. At last count, gamers were averaging more than 51 hours with the game, which has sold more than a million copies, according to reporting I've done in the past. Only three games boast more hours per player: The similarly multiplayer-centric Super Smash Bros. Brawl and Guitar Hero III along with Animal Crossing: City Folk, a game designed to be played daily.
