Family Guy Online is now open, and the game is assigning waves to interested Quahog residents moving forward. The "Keys to Quahog" program will be assigning times to new registrations as the game goes through beta testing, on a first-come, first-served basis.
The Family Guy Online site details the program, which will queue up users. Keys will give the day and time you can enter, and new registrations will get an approximate wait time to receive their key. Beta registrations have been open since last year, so those who signed up early are at a distinct advantage. If you want to become a resident of Quahog yourself, registrations are still open.
