"40 characters and 30 stage" Whoa whoa whoa, slow down there. 1) I'm pretty sure you can't have "Smash Bros." in the title due to copyright. 2) You can't use copyrighted characters like Mario, Link or Sonic, BTW. 3) As I said, slow down! Don't plan too far ahead. Make a basic testing character and stage first. One of the only fighting games in SB ever made only has one stage and two characters.
