(Wii) Super Mario Galaxy 2

Originally planned as an expansion of Super Mario Galaxy released in 2007, the features introduced convinced Nintendo to release a brand new game, published in 2010.
Super Mario Galaxy 2 gameplay is similar to its predecessor and adds the control of Yoshi, some stages with dynamic environments and new power-ups; another feature to mention is, similar to New Super Mario Bros. Wii’s Super Guide, the Cosmic Guide, which appears if the player fails too many times in a particular level and assumes the control of Mario to finish the stage (but doing this way the player is granted only with a Bronze Star).
The Japanese version, as the European one, comes with an original cardboard box and a special DVD featuring videos for basic controls and advanced play.
