20. Batman: Arkham Asylum (2009)
Final Level: Last Laughs
Why It Sucked: Arkham Asylum is one of the greatest licensed games ever made, but boy did its ending jump the Batshark. All of the Joker's subtle manipulations and machinations end with him injecting himself with crazy pills and challenging Batman to a duel? That's so out of character we think it must have been a joke that the writers forgot to write out before the game went into production.
How We Would End It: We didn't want the Joker's storyline to end with an actual joke—he would have gone out with a bang and maintained a shred of his peculiar brand of dignity in our version.
