Yuji Naka, the creator of Sonic the Hedgehog recently told Famitsu that he always wanted to see Sonic and Mario pairing up in their own action game. While both have appeared repeatedly in the Mario & Sonic at the Olympics titles for Wii and DS platforms, they have yet to meet on a platformer.
Sure, they’ve also beaten each other black and blue in Super Smash Bros Brawl, but to see the blue blaze and the plumber teaming up to take down evil together would be something special, if it could work.
“Actually, I wanted Mario [and Sonic] to appear together, so one time I went to give Miyamoto-san a presentation on how I want to create an action game which is co-starred by Mario and Sonic. It was in the GameCube days, and I took around four planners with me. It is a pity that the discussion was ‘clearly it isn’t necessary for Mario and Sonic to co-star in an action [game]’ and it didn’t become a reality, but SEGA was able to get the license for the Olympics just at that time, so in order to make the best use of the license, companion characters appeared together. A little later Sonic appeared in Super Smash Bros. Brawl. However, this too came into reality because I requested from Sakurai-san, ‘I want Sonic to appear [in Smash Bros.]’. The Olympics is a bit different from my wish, but I think it’s a good thing that children around the world are happy about them co-starring. But someday I want to realize an action [game] together with Mario. I think I’m going to give another presentation so that Takashi [Iizuka] finds the necessity [of a Mario & Sonic action game] (laughs).
“I also agree. Previously they were considered rivals, but when I saw them co-starring, I honestly thought that Nintendo acknowledged Sonic.” Original Sonic designer Naoto Ohshima
Throughout the 90s, Mario and Sonic both battled for popularity during the original console war. You either loved SEGA, or you loved Nintendo. Why not both?! Mario clearly won, with his higher quality titles, and SEGA not knowing what to do with Sonic, jumping between 2D and 3D trying to find his footing again.
