Granted, but once you do, you realize the terrible truth: The source of its problems was actually a terrible demon, sealed in there at the time of manufacturing. By breaking the warranty seal, you cut the wards keeping him in place, and he escapes to lay ruin to the world.
Realizing your mistake, you set out to find and slay the demon, teaming up with a cute chick (who turns out she likes you), a mean bruiser who is actually kinder than he looks, and an anthropomorphic creature who has nothing better to do than help you. You go on all sorts of wacky adventures, some ending in victory, some in defeat, and even get killed at one point (but, don't worry, you're brought back by some kind of deus ex machina!).
Finally as you track the demon down, another revelation strikes you as you realize that you were manipulated from the very beginning by a third party, who sought the release of the demon for his own dark designs. Even though you'd travelled so far, you don't get a chance to actually fight the demon. Instead, you get a chance to beat up... a frail old man. Oh! But he's turned into a monster now, so that's okay!
Then, as he lays on the ground, slowly dissolving into the air around him, he tells you one last thing: "I'm sorry, son."

I wish I weren't so clichéd.
