Street Fighter II was an enormous success upon release in arcades worldwide in early 1991 by Capcom Co., Ltd. It became a massive hit across various platforms such as arcade machines, home console systems including Super Nintendo Entertainment System (SNES) and Sega Genesis/Sega Mega Drive outside North America.

The game's storyline follows from Street Fighter: The World Warrior where the main character must travel around the globe to compete in an illegal fighting tournament organized by powerful businessman Mr. Bison (also known as Vega in some regions). Players can choose between eight characters, each with their unique moveset and special abilities such as Ken Masters' Hadouken fireball attack or Ryu's Dragon Tiger Fist move.

Street Fighter II introduced several innovative features that set it apart from other fighting games at the time:

1. The 'Fatalities' system allowed players to perform finishing moves on defeated opponents after a certain amount of health was drained.

2. A 'Super meter' gradually filled up during matches when performing combos or special attacks; once full, the player could access their respective Super move for increased damage potential.

To further enhance gameplay experience and encourage competitive play among fans worldwide:

1.) Street Fighter II introduced Rank system allowing players to rank themselves based on performance within local multiplayer mode - this encouraged friendly competition amongst friends while playing together at home or arcade centers alike!

2) Another significant addition was 'VS Mode,' which allowed two human players versus each other in one-on-one matches without need for AI opponents present anymore! This feature greatly contributed towards popularizing Street Fighter II among hardcore gamers everywhere.

Overall, the combination of fast-paced fighting action combined with its engaging storyline made Street Fighter II an instant classic upon release.
