Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ, Sonikku za Hejjihoggu) is a platform game developed by Sonic Team and published by Sega for the Mega Drive/Genesis system. It is the inaugural game in Sega's flagship Sonic the Hedgehog video game series, and was the first title developed by Sonic Team. The game was released in 1991 in North America, Europe, and Japan. It is sometimes retroactively referred to as Sonic the Hedgehog 1 or Sonic 1 to differentiate it from both its main character and sequels in the same series.

Gameplay

A typical in-game screenshot of Sonic the Hedgehog, taken from its first level, Green Hill Zone.

In the game, Sonic has to prevent Dr. Robotnik from collecting the six Chaos Emeralds in an attempt to rule South Island. The player controls Sonic as he traverse six zones of three acts each. At the end of the third act of each zone, the player faces Dr. Robotnik in one of his vehicles.

The gameplay centers around Sonic's ability to run, jump, and roll at high speeds. Levels include springs, slopes, high falls and loop-de-loops, to allow the player to achieve high speeds. Essential to the gameplay are the signature power rings the player collects, which are regularly placed around the level map. While Sonic possesses at least one power ring, the player will not lose a life when injured. Instead, the rings the player has collected will fly outward from Sonic which can then be retrieved before they disappear. If the player runs into an enemy without possessing any power rings, he will lose a life. The game is over, when you lose all this lives.

Despite the various types of protection available, neither the shield, power rings, nor invincibility will prevent the player losing a life if Sonic is crushed (by a trap or between a wall and a moving platform), drowned, passes the ten-minute time limit, or falls into a pit.

Progression through the game is made easier for the player by lamp posts that act as checkpoints. When Sonic passes a lamp post, the game will resume from that point when the player loses a life. In the Japanese version, if a checkpoint is activated and a life is lost as a result of running out of time, the time at the checkpoint will reset to 0:00.

Hazards the player experiences include a wide variety of "badniks" - these appear as animals trapped inside mechanical bodies which are released the moment the player hits them. Each badnik takes one hit to destroy, but they vary greatly from Zone to Zone; some will walk in a set path, others will try blasting the player, and some cannot be avoided at all. The player must also avoid rows of sharp spikes, cliffs, and elaborate death traps. There is also the threat of drowning, as the player can only survive approximately 30 seconds underwater (locating air bubbles can extend this).

Development

Development for Sonic the Hedgehog began in April 1990, after Sega ordered its AM-8 team to develop a game featuring a mascot for the company. After choosing a hedgehog as the main character, the 5-person group changed its name to Sonic Team and started working on Sonic the Hedgehog. The main minds behind the game were character designer Naoto Ohshima, game programmer Yuji Naka and designer Hirokazu Yasuhara.

The game was originally intended to feature a sound test menu, with animated graphics based around Sonic break-dancing to the music of a "Sonic Band" consisting of Sharps Chicken (guitar), Max Monkey, (guitar), Mach Rabbit (drums), and Vector the Crocodile (keyboard/synth); Vector was later re-designed and re-used for the games Knuckles' Chaotix and Sonic Heroes. The development schedule meant that the feature had to be scrapped, and Yuji Naka decided to replace the test with the "SEGA!" chant used in TV advertisements, which took up 1/8 of the 4-megabit cartridge. A text-only sound test option remained in the final game's level select cheat menu.

This is the only Mega Drive/Genesis Sonic game made entirely in Japan. Although Sonic the Hedgehog CD was made in Japan as well, Sonic the Hedgehog 2, Sonic the Hedgehog 3, and Sonic & Knuckles were produced in North America at Sega Technical Institute, albeit with almost exclusively Japanese staff members. Sonic the Hedgehog Spinball, however, was produced almost entirely by Americans, the only Sonic game to date to do so. Sonic 3D featured Japanese staff, but much of the work was done by the UK-based video game company Traveller's Tales, who also produced Sonic R.

Music

Sonic the Hedgehog uses the on-board Zilog Z80 and Yamaha YM2612 synthesizer sound chip to produce a variety of stereo sound effects and music. The game has been praised for its dynamic music, composed by Masato Nakamura, a member of the popular J-Pop band, Dreams Come True.

Character art and game packaging

Akira Watanabe, the illustrator of the character art, said that his sole goal was to depict the characters as "colorful" and to use clear cutting lines and gradation to "finish them neatly."

Watanabe said that the developers asked him to create a package design "similar to pop art." Watanabe aimed to create the design "without being particular to conventional packages." Watanabe intended to create an "original, stylish pop game package."

Versions and releases

The first version, released in North America and Europe, lacked some graphical enhancements that were added to the Japanese release a month later. The Japanese version included clouds that moved independently of the scrolling background (even when the main character stands still) in the Green Hill Zone and two water graphical effects in the Labyrinth Zone, which consisted of a rippling effect on the foreground and a swirling effect on the background. This effect was only applied to the areas that were under the water line. Also in the Japanese version, all levels of the game had many more layers of parallax scrolling in their backgrounds.

The first version also gave the player an enormous 250,000 point bonus if a stage was cleared in less than 30 seconds. Subsequent revisions cut the bonus down to 50,000.

The later Japanese version 2.0 fixed the "spike bug" (a bug in which Sonic would instantly die if he "bounced" from one set of spikes to another due to him not gaining temporary invincibility until his feet touched the ground). Also fixed in both Japanese versions is the level select cheat, which listed the game's levels in an erroneous order.

In addition to this, due to differences between standard PAL and NTSC refresh rates (50 Hz and 60 Hz respectively), the European version of the game plays at about 83% speed of the NTSC version, and the music is also slowed down by the same amount. Subsequent PAL Mega Drive games and some of Sonic 1's re-releases (e.g. Sonic Jam) retained the NTSC versions' correct music speed, although the gameplay remained slower.

8-bit version

Main article: Sonic the Hedgehog (8-bit)

Sonic the Hedgehog is a video game that was released for the Sega Master System and the Game Gear. Though based on the Mega Drive game of the same name, it is a distinct game, with different level designs, and three of the six zones (worlds) based on original themes. The Sega Master System version was the final title for the console released in the USA and is now on the Wii Virtual Console, released in North America on August 4, 2008 and in Europe on September 19, 2008. The Game Gear version has appeared with other titles on Sonic Adventure DX for GameCube and PC and Sonic Mega Collection Plus for PlayStation 2, Xbox, and PC. A conversion for Palm Tungsten handhelds was also released in 2003 by Sega Mobile.

Sonic the Hedgehog Genesis

A new version of the game, which was entitled Sonic the Hedgehog Genesis, was released for the Game Boy Advance in November 2006 as part of the celebrations of the original game's 15th anniversary. The game is a remake of the original game as opposed to a port. It includes a new save feature and a special "Anniversary Mode" featuring the Spin-Dash move that was added in later games. In addition, the view is slightly zoomed in and adapted for the GBA's widescreen aspect ratio, and the level select and debug codes have been left out, the former due to the fact that there is already a zone select screen. The reception was negative, as many reviewers criticized the game for its slow frame rate, music, and glitches—most called the game "unplayable."

Compilation releases

Compilations that include the game are Sonic Compilation (1995) and Genesis 6-Pak (1996) for the Sega Genesis; Sonic Jam (1997) for the Sega Saturn; Sega Smash Pack (1999) for the Sega Dreamcast; Sonic Mega Collection (2002) for the GameCube; Sonic Mega Collection Plus (2004) for the PlayStation 2, Xbox and PC, SEGA Mega Drive Collection PSP and Sega Genesis Collection (2006) for the PlayStation 2 and PlayStation Portable, and Sonic's Ultimate Genesis Collection for the Xbox 360 and PlayStation 3.

Sonic Jam features four different modes of playing Sonic the Hedgehog: "original", identical to initial release; "medium", which affects the layout of rings and hazards; "time attack", which uses the "medium" level maps and allows players to save their record times to 1/100 second; and "easy", which removes certain Acts entirely from the game. In addition, an option setting alters can alter the game to allow the use of the Spin-Dash, a move that did not debut until Sonic 2 the following year. The spike bug from earlier versions of Sonic the Hedgehog can be triggered if Spin Dash is turned off.

Sonic Mega Collection and Mega Collection Plus feature all three revisions of the game. The GameCube PAL edition of Mega Collection for the GameCube supports a 60 Hz option, which not only allows the game to be played full-screen and at its original speed, but also allows either the US or Japanese version 2.0 iterations to be played via a cheat code (the first Japanese version is the default). If the 50 Hz option is selected, these cheat codes do not work and only the PAL edition of the game can be played.

Both the US and European releases of Sega Genesis Collection contain the US version of Sonic the Hedgehog.

Releases on other platforms

A Java ME conversion for mobile phones running Java was released by I-Phone in 2006. This version, Sonic the Hedgehog Part 1, includes only the first three zones, with the remainder released as Sonic the Hedgehog Part 2 by Glu Mobile in 2007. This version mostly follows the Mega Drive version, but some features have been removed, most notably the Special Stage. There has also been a second, not as widely known version the game for Verizon phones, that has everything the original version did, although strangely removing all sound effects from the game. The mobile phone version also came bundled with some Panasonic cell phones in Europe and Japan.

In 2006, Sonic the Hedgehog became available for Nintendo Wii's Virtual Console service from launch, and in 2007 entered Xbox 360's Xbox Live Arcade, under the title Sonic the Hedgehog Arcade. The 360 version does not allow the use of cheats to prevent undue earning of Achievements. It also has options for graphic smoothing, saving and loading current progress in-game and to resize the gameplay window.

The game was also present on the Danger Hiptop's Sidekick 3, Real Arcade and GameTap (along with most classic Sonic games).

In response to the negative reception of Sega's port on the Game Boy Advance, a programmer named Stealth released a proof-of-concept version of Sonic 1 to the Game Boy Advance by using the original Genesis version's data from disassembly.

In 2004, Sega released Sonic The Hedgehog for PlayStation and the PlayStation Store for the PlayStation Portable and PlayStation 3.

In 2007 the game was made available on the iTunes store as a game for the iPod nano with video, the iPod classic, and iPod with video.

Sonic the Hedgehog appeared next in Sonic's Ultimate Genesis Collection for Xbox 360 and Playstation 3, along with many of the series subsequent games.

In early 2009, Sega announced that the game would be available for Apple's iPhone OS in the Spring.

Legacy

Sonic the Hedgehog greatly increased the popularity of the Genesis in North America. After it was released, it eventually replaced Altered Beast as the game bundled with the console. In large part due to the popularity of this game, the Genesis outsold the Super Nintendo nearly 2 to 1 during the 1991 holiday season. This success led to Sega overtaking Nintendo in January 1992 with control of 55% of the 16-bit console market, making it the first time Nintendo was not the console leader since December 1985. The game featured many novel elements which contributed to its popularity and helped to promote the uptake of 16-bit consoles. The game is widely considered to be one of the greatest games of all time, placing #63 on IGN's 2007 list.

Sonic the Hedgehog added the element of speed to the standard platform formula and introduced other unique elements as well, such as the loops, springboards, high-speed devices, and the rings now permanently associated with the game series.

The game was both a critical and commercial success. As of November 19, 2007, the game has sold 4 million copies, the second-highest amount for a Genesis game, behind Sonic 2, which has sold 6 million copies.
