Smash also has a 30 plus hour single player mode with a crap ton more interactive stages to fight in. The comparison is completely fair and again, it puts these devs to shame.
Wrong. You obviously have not played Dead or Alive 6. The stages are the most advanced and interactive of any fighting game in history. Smash isn't even 3D.
Second of all, does smash have story cutscenes for every character in the game in addition to the main story? Give Team Ninia a break.
