Family Guy Online was massive multiplayer online role-playing game, or MMORPG for short, which is developed by Roadhouse Interactive for 20th Century Fox in conjunction with lead developer Acronym Games. Family Guy Online is based on FOX's animated sitcom series Family Guy, created by Seth MacFarlane. The game was an open beta, free to play, to players. Although the game was free to play, the game required Unity Web Player. As of January 18, 2013, the game has been shut down, and it will not leave beta.

The game gives the player the opportunity to become a Spooner Street neighbor, interact with other players, and do tasks amongst many characters. First, the player creates several characters from different Character Classes, which will influence the appearance of the character, and how that character will play inside the game.
