Sonic the Hedgehog 2 was developed by Aspect with co-operation from
Sega, unlike its predecessor which was developed by
Ancient. Craig Stitt, who worked as a stage artist with
Sega Technical Institute (STI) on
Sonic 2 for the Sega Genesis, stated that there was little interaction between Aspect and STI. Both versions of
Sonic the Hedgehog 2 were released in
PAL territories on November 24, 1992. The
Game Gear version was released in Japan on November 21 and in North America in December 1992. It was the first four
megabit cart for the Game Gear, the largest yet. The Master System version remained exclusive to PAL territories until it was released in December 2008 for the
Wii Virtual Console. The Game Gear version was included as an unlockable bonus in
Sonic Adventure DX (2003), and as one of the games featured in the
Sonic compilation
Sonic Gems Collection (2005). It was also released on the
Nintendo 3DS eShop in June 2013. It was also released along with the other 11 Game Gear
Sonic games on
Sonic Origins Plus in 2023. In the United Kingdom, all versions of
Sonic the Hedgehog 2 (including the 16-bit
Sonic 2) combined topped the Christmas 1992 sales charts. For the month of December 1992, the Mega Drive version was ranked number one, the Game Gear version number three, and the Master System version number four, while
Super Mario Land 2 for the
Game Boy was number two.
Sonic 2 is the bestselling Game Gear game, having sold over 400,000 copies. ==Reception==
