The prophecy of the chosen one was made just as a scam by the main villain so someone with more or less your powers would gather the macguffins for him. In fact, if he hadn't used you he could have easily used another guy like guy several years down the line.
Lot of JRPGs make you play as some mundane faggot who accidentaly gets involved into something bigger than him.
>you look strikingly similar to the chosen one
>as such, you have been mistakenly identified as him
>Instead of fighting God at the end you are God's chosen warriors
>you can't leap that wall because you're not so great
Grandia 2 was a great one that did that, just off the top of my head.
>You are the Chosen One, maybe, probably.
>You find the corpses of people who thought they were the chosen one throughout the game.
>The game mocks them through song each time.
>At the end of the game, you decide if you are the Chosen One or not.
Wasn't Dark Souls (inb4 deepest lore) something like this?
Turns out, the Chosen One thing was just some bullshit made up by the He-She Moon God to trick some stupid schmuck into doing a lot of leg-work, killing some dangerous monsters, then lighting themself on fire to burn for all eternity to restore the power of the Gods?
At the end, you can sacrifice yourself anyways, to free humanity from the curse of undeath; or you can say fuck it and let the Gods' power crumble and rule the Earth yourself. And probably turn into a mindless zombie.
