Maxwell returns, this time in HD and with even more ways for gamers to draw their own ideas into the game. Nintendo showed a new trailer (watch after the break) previewing some of the new features for the next Scribblenauts title, Scribblenauts Unlimited. The game will be released on both the Wii U and 3DS. In addition to allowing players to create and share their own items, the developers hint that this game will finally reveal the story behind Maxwell’s magic notebook.
