Sonic the Hedgehog Pocket Adventure
In August 1999, SNK announced that they were collaborating with Sega to develop a "Sonic the Hedgehog" game for their Neo Geo Pocket Color handheld system. The game was developed by SNK, with supervision from Yuji Naka and Sonic Team at Sega. This marked the first time Sega was directly involved in the development of a "Sonic" game for a non-Sega platform. The team planned for "Sonic Pocket Adventure" to be a return to the classic 2D gameplay style found in the "Sonic" games on the Sega Genesis. In particular, many game design and visual elements are borrowed from "Sonic 2". The game's background music tracks are also 8-bit renditions of music from "Sonic 3". "Sonic Pocket Adventure" was released first in North America on December 4, 1999. SNK released a system bundle with the game included for the holiday season. The game was released in Japan two weeks later, and in Europe in February 2000.
Sega Saturn
Journalists and fans have speculated about the impact a completed "X-treme" might have had on the market. David Houghton of GamesRadar described the prospect of "a good 3D "Sonic" game" on the Saturn as "a 'What if...' situation on a par with the dinosaurs not becoming extinct." IGN's Tavis Fahs called "X-treme" "the turning point not only for Sega's mascot and their 32-bit console, but for the entire company", but noted that the game served as "an empty vessel for Sega's ambitions and the hopes of their fans". Dave Zdyrko, who operated a prominent Saturn fan website during the system's lifespan, said: "I don't know if ["X-treme"] could've saved the Saturn, but ... "Sonic" helped make the Genesis and it made absolutely no sense why there wasn't a great new "Sonic" title ready at or near the launch of the [Saturn]". In a 2007 retrospective, producer Mike Wallis maintained that "X-treme" "definitely would have been competitive" with Nintendo's "Super Mario 64". By contrast, "Next Generation" reported in late 1996 that the game did not compare well to contemporary competition, and would have harmed Sega's reputation if it had been completed and released. Naka stated that he was relieved by the cancellation, as the game "wasn't looking very good from my perspective".
