I hope Kotal Kahn's Tower Ending ends up as canon - the notion that the cycle can't be broken. Raiden's gone dark. He's after Kahn after his aggressiveness at the end of story mode. I absolutely love love love love the idea that maybe we get a new tournament that almost puts Outworld in the "protagonist" column *with* Earthrealm. I love the notion that maybe it becomes less Outworld vs. Earthrealm, but Outworld vs. Earthrealm/Netherrealm or Outworld vs. Earthrealm vs. Netherrealm.
I could see the dilemna on our new heroes faces. Do they really want to fight to the death in this damn tournament because Raiden was an aggressive SOB? I could see them trying to find a way to call it off. I could see Sub Zero and Scorpion taking Raiden's place as the overall mentors to the group. I'd see Johnny, Sonya, Kenshi, and Jax maybe fading away and or dying in the scuffles. New characters. New conflicts. Klassic Kharacters. Klassic Konflicts.
My dream MK11 would be a new MK Tournament. Raiden and Kotal would duke it out. Fujin would take Raiden's place as Protector of Earthrealm. The Revenants would be destroyed. Goro would make a play for the throne and betray Outworld again (maybe helping Earthrealm to try and win the throne that way.) I would see dilemnas for Earth with loyalties being tested. (Is Sub Zero willing to play into Raiden's dark aggression for example, or does he discover more about the Chryomancers and thus side with Outworld. Does Raiden do something to trigger the rage in Scorpion?)
... and I would see the return of Shao Kahn. I know that people are tired of him. But I would love it if the final match of the Story Mode was Kotal vs. Shao Kahn. New Emperor vs. Old Emperor. The fate of Outworld/Edenia/Earthrealm on the line. I really do love Kotal now, and feel like he's the closest thing to a "good" Outworlder we've got that wasn't Edenian.
