刺猬索尼克2 (8位机版)

ソニック・ザ・ヘッジホッグ2

Sonic the Hedgehog 2 (ソニック・ザ・ヘッジホッグ２) was made in Japan by Aspect Co. Ltd for the Sega Master System and later ported to the Sega Game Gear. Even though it shares its name with the 16-bit version of Sonic 2 for the Sega Mega Drive, it is not a port, as it contains entirely different levels. It was released slightly before its 16-bit namesake, making this game host to the first appearances of both Miles "Tails" Prower and Mecha Sonic. The Game Gear version contains noticeable differences from the Master System version. The changes made in the portable version give it a reputation of being one of the hardest Sonic games in existence. Some choices appear to have been intentional, by design: for example, the boss music is different and some boss areas have different layouts. However, many of the difficulties in the GG version result from its smaller screen and its scrolling: the player is left more open to being hit, in a way that some might label 'cheap', due to not being able to see obstacles and enemies around them but beyond the range of the screen. The scrolling is the same in the Master System version, but it is not as big a problem as more of the surroundings can be seen.
