Walt Disney's The Jungle Book is a series of video games based on the 1967 Disney animated film The Jungle Book, primarily released in 1994. It was first released by Virgin Interactive in 1993 for the Sega Master System. Conversions for the Game Boy, NES (for which it was one of the last titles released by a third-party developer), Sega Mega Drive/Genesis, Sega Game Gear, Super NES, and PC followed in 1994, and a remake for the Game Boy Advance was released in 2003. While gameplay is the same on all versions, technological differences between the systems forced changes – in some case drastic – in level design, resulting in six fairly different versions of the 'same' game. This article is largely based upon the Sega Mega Drive/Genesis version.
