42. Eternal Sonata (2007)
Final Level: Heaven's Mirror
Why It Sucked: There were a lot of cool things about this game that went unrealized. For one thing, Frederic is supposed to be dreaming the whole thing, which is a bit of a cliche. But then it turns out he's actually not dreaming it. Then Polka kills herself, which is great, but she gets to come back to life because she's in love, which is great for her, but not for the narrative.
How We Would End It: Polka should have stayed dead and the world should have ended when Chopin died, just like when Link wakes up the Wind Fish in Link's Awakening. Spoilers!
