I'm not sure this would qualify as a bad ending, but: I got too emotionally involved in the in Zelda OoT when I played it as a 14 year old, and the end made me feel rather shitty. Maybe it's pointless, but I wanted to explore the "fixed world" a bit. I realize that's like a bit too much to ask from a game. If nothing else, I would have liked a propper happy ending, not that magical-mystical-philosophical crap of being sent to the bast to be a kid again because you lost your childhood or something. Like, whatever you did doesn't matter anymore. What is supposed to happen now? Will link just convince Zelda to refrain from trying to fix anything because it ends badly? Will Gannondorf just sit idly because he can't get his victory without you? Also, WTF, Zelda! Mario got a kiss and a cake! You got me into this crap for which I risked my fucking life and you are just going to tell me "Good job, I'm so sorry, bye!"??? stingy selfish bitch!
