I think his appearance on this game will be more well received than Noctis in Tekken because no one is playing Noctis in Tekken. On the other hand I can see a lot of people playing as Sephiroth. Cloud is already on the game so that is an additional factor to make more people want to play him. Sephiroth stabbing Mario is one of the coolest scene ever. He really looks intimidating on this trailer. I hope to see more Final Fantasy characters on this game.
