8. Shadow Of The Colossus
In one of the most memorable titles from the PS2 era, you find yourself on a quest to hunt down and slay 16 giant creatures in order to save the love of your life, called Mono. If a little predictable, the game's big twist is still no less effective for it, as once you defeat the last of the Collossi, it quickly becomes apparent that they weren't actually all that bad, they were the only things standing in the way of keeping the evil demon Dormin from returning from his long slumber. Upon awakening you become possessed by him, before eventually being transformed into a horned demonic infant who at the end of it all comes into the care of Mono. It's no Hollywood ending that's for sure. Not only do you feel cheated and used after battling all 16 Collossi, but you end up being physically used by the game's real antagonist. In the end you do get the girl, but it's by no means in the way you intend to when you first set off on your adventure.
