They also did Ninja Gaiden. They have also made a few fighting games before, in the Dead or Alive series. So they have some experience there! They also did Hyrule Warriors which was not complete destruction of the source material.

So, they have one "bad game", which people only complained about the story/characterisation of. Not the gameplay. Which does not matter in fighting games. At all.

So... what is the issue, again?
