At Family Guy: The Quest For Stuff (FGTQFS) the character unlocking system is different. You have to unlock districts where you can build a specific building with a character attached. Building the structure isn't enough, you also need to let your other characters complete tasks to find items that are needed to unlock the character.

Also at FGTQFS it is possible to earn premium currency by watching short (30 seconds or shorter) ads. This way it's easier to buy premium characters without having to pay for it with real money.
