Wolfenstein 3D
Although id Software did not develop another "Wolfenstein" game, as their development focus shifted to "Doom" shortly after release, and has never returned to the series, multiple "Wolfenstein" titles have been produced by other companies, sometimes using game engines developed by id. The first of these newer "Wolfenstein" games was "Return to Castle Wolfenstein" in 2001, a reboot of the series, and the latest is the 2017 "".
Return to Dark Castle
Return to Dark Castle is a 2008 platform game for Mac OS X developed by Z Sculpt. It is the third and final game in the Dark Castle series, following "Dark Castle" (1986) and "Beyond Dark Castle" (1987). Development on the game, begun in 1996, was notoriously protracted, and the game was often labeled vaporware. "Return to Dark Castle" was originally scheduled to be released in Winter 2000, but was not released until March 14, 2008. It brought colour to the original black and white graphics, and integrated the gameplay and levels of both the original games.
