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.
Sonic Team
Sonic Team has developed a number of video games, with many of them becoming bestsellers. The studio is best known for its "Sonic the Hedgehog" series of platform games, which account for the majority of Sonic Team's work; the 1991 release of "Sonic the Hedgehog" is considered one of the most important moments in video game history, as it propelled Genesis sales and displaced Nintendo as the leading video game company. Sonic Team have also developed a wide variety of other games, including action games such as "Nights into Dreams", "Burning Rangers", and "Billy Hatcher and the Giant Egg," the online puzzle game "ChuChu Rocket!", the online role-playing game "Phantasy Star Online," and the music game "Samba de Amigo". "Phantasy Star Online" is credited for introducing online RPGs to consoles and was the first online RPG for many players. According to Sean Smith of "Retro Gamer", few companies could claim to have released as many AAA games over such a long period, especially between 1991 and 2000. Some Sonic Team games, such as the original "Sonic" games for the Genesis and "Nights", are considered some of the best video games ever made.
