Despite the movie featuring characters from Nintendo, Sega, Capcom, Atari, and other game publishers; the Wreck It Ralph game will only be found on Nintendo platforms. Activision announced the game for the Wii (not the Wii U apparently), the 3DS, and the DS. It sounds like it’ll be a two-player platformer, probably taking after Sony’s Ratchet series.
As the game is being published by Activison, and it’ll only be on Nintendo’s platforms, it’s probably doubtful that any of the cameos that make the movie look so awesome would make it over. This isn’t too surprising, as when they made Who Framed Roger Rabbit? games back in the late 80′s and early 90s, they only featured the original characters from the movie.
