Nintendo is for children. Sonic is for adults.

Y3 ending probably but not really but maybe [spoiler]So of we go by the mysterious ending and how it ended abruptly having us just teleport back to Eris, we can assume that they stole our identity. This could also correspond to the events of the Chronicon and how we end up killing everybody. The Chronicon is basically everyone's biggest insecurities, Drifter's hunger, Amanda's friendship, Ikora being tested to name a few. Even Taken abilities are those insecurities emboldened into a new shape. With us would be what exactly? Pretty much the opposite of what we currently are, which is the hero of the story. While our doppelganger parades around as the hero for a while, with us being imprisoned by the Unknown Artifact, someone.. a sister of three comes to our aid. That is how we will meet Savathun, while she invades on the Leviathian. She opens a portal to lure ourselves in and we swap back, imprisoning the doppelganger giving Savathun full control of the pyramid. The Witch Queen vs the Shadow Queen. [/spoiler]
