NiGHTS into Dreams was originally released for Sega Saturn in 1996. The game achieved great critical successes and, almost immediately, became a cult video game.
However, gamers had to wait more than 10 years for a sequel. NiGHTS: Journey of Dreams was released for Wii in 2007.
Today, Sega filed a trademark for “Nights Dream Wheel” in Japan. At the moment, no sequel has been announced, so the nature of this trademark is quite confusing.
