Steel Empire (originally released as Koutetsu Teikoku (鋼鉄帝国?) in Japan, and otherwise known in various English materials as The Steel Empire or Empire of Steel) is a side-scrolling shoot 'em up video game released on the Sega Genesis / Mega Drive home consoles in 1992, and was later ported to the Nintendo Game Boy Advance in 2004. Steel Empire is notable amongst shoot 'em up games for its unique aesthetic designs. Mostly low-tech in nature, with its being set in the late-19th century of an alternate world, the game's aircraft, weaponry, powerups, environments, enemies and bosses are heavily stylized adding strong steampunk elements to the style, themes and visuals of the game. Steam power, propeller-based aircraft, biplanes, dirigibles and heavily armored steam trains with giant cannons play large roles in the game's protagonists and opponents. The original leaked Japanese arcade beta version (now rare and the source code of which is believed lost), the popular Mega Drive version and the GBA remake were all critically well received. As of 2012, a modern, "gritty" sequel, Burning Steel, is planned by original HOT・B lead game designer Yoshinori Satake for a 7th generation and possibly an 8th generation console.

Street Fighter II': Champion Edition (ストリートファイターIIダッシュ -CHAMPION EDITION-?) is a competitive fighting game released for the arcades by Capcom in 1992. It was the first of several updated versions of the original Street Fighter II: The World Warrior. The main changes consisted of the addition of the Grand Masters (the final four computer-controlled opponents in the single-player mode) as playable characters and mirror matches (same character vs. matches). The fighting techniques of the eight main characters from the original game were also further refined to allowed for more balanced competitive play. Champion Edition was followed by Street Fighter II' Turbo: Hyper Fighting, released several months later.

Streets of Rage (ベア・ナックル 怒りの鉄拳, Bea Nakkuru: Ikari no Tekken?, "Bare Knuckle: Furious Iron Fist") is a side-scrolling beat 'em up released by Sega in 1991 for the Mega Drive. It is the first installment of the Bare Knuckle/Streets of Rage series which was followed by Streets of Rage 2 and Streets of Rage 3. The game was also converted over to Sega's Game Gear, Mega-CD and Master System. In 2007, the game was released for the Wii's Virtual Console in North America and Europe, and in 2009 it was released for the iOS via the App Store. The game was again made available as part of Sonic's Ultimate Genesis Collection in 2009 on both the PlayStation 3 and Xbox 360 consoles. There was also a comic strip series based upon the games which appeared in Sonic the Comic. These three stories are based on Streets of Rage 2 and do not feature Adam. The game features an acclaimed chiptune soundtrack by Yuzo Koshiro, who released it as an album in the Japanese music market.
