Can't wait for John 3! Of course, I won't spoil the ending of John 2, you should play it yourself to find out.
John 2 is such a good game because it comes back from a cliff hanger, when John destroys a burger king in John 1, he runs out on fire, and gets arrested! In John 2, it shows the perspective of him in prison. In John 2, a man by the name of Gerald is trying to take power in the Wendy's hierarchy, and thus banishes John to get the secret formula to the krabby patty, and learns the truth about Wendy's.
