Answer 1

 Seriously guys?. . . is this a serious topic. . . Its world of warcraft by A HUGE margin. World of Warcraft has 11.8 million active subscribers (according to Blizzard's statistics), which would put WOW's GDP at  $2.124 B / year plus initial game and expansion purchases totalling $60 per player.

Warcraft makes more then ALL of them put together in a single year. . . and it's in it's 6th year now.
