Released in May 2006, Big Fat Awesome House Party was a MMO-like game. You could create your own Imaginary Friend and go on adventures with Bloo in and around Foster's Home for Imaginary Friends. The game held a depth that most Cartoon Network browser games lacked, which caused it to become hugely popular with fans. The game was only originally going to last until April 2007 however its popularity caused it to last until July 2009 (the same year the cartoon ended). At the end of its lifespan it had over 13 million players.
