《快打旋風2》(Street Fighter 2):自1991年問世以來，推出多個版本，每個版本都帶來不同的變化和改進。以下是這些版本的詳細介紹：

快打旋風 The World Warrior (1991年3月):首個版本，率先在街機推出，採用卡普空CPS1基板。玩家可以在8位角色中挑選一位進行遊戲，擊敗其他7位對手後，會出現隱藏的4位頭目。

快打旋風 冠軍版 (Champion Edition) (1992年3月):角色數量增加至12位。首次加入2P功能，允許兩位玩家使用身穿不同顏色的同樣角色進行對戰。此版本非常受歡迎，市場上出現各種衍生的破解版。

快打旋風 極速版 (Turbo) (1992年12月):主要針對破解版及盜版問題進行部分bug修補。人物招式進行調整，例如春麗(Chun Li)新增波動拳，達爾希姆(Dhalsim)可以瞬移。遊戲節奏大幅加快。

快打旋風 新的挑戰者 (New Challenger) (1993年9月):基板更新到卡普空CPS2，角色增加至16位。角色頭像及音樂全部重製，節奏與冠軍版一致。大幅度改變必殺技招式，例如隆(Ryu)可以使用火焰波動拳，肯(Ken)的重擊昇龍拳可以讓對手燃燒。導入連續攻擊的要素，支持最多4台街機連線進行8人錦標賽。根據比賽結果，玩家會被分成勝利組和失敗組，然後進行2對2的競技。總共有三輪比賽，最終確認8位玩家的排名。由於對設備的要求高，並且玩家需要頻繁更換位置，導致這種比賽形式在當時的普及率並不高。

快打旋風 Grand Master Challenge (1994年3月):在日本以外稱為Turbo，遊戲節奏再次加快。新增集氣欄位與超必殺技系統，整體速度為系列最快。可在遊戲中自行調整速度，首次引入超人氣頭目豪鬼(Akuma)。只要在遊戲中沒輸過一局，在最終舞台挑戰維嘉(M.Bison)時，豪鬼就會出現.一個瞬獄沙就解決維嘉。

Since its debut in 1991, "Street Fighter 2" has released multiple versions, each bringing different changes and improvements. Here is a detailed overview of these versions:

Street Fighter 2: The World Warrior (March 1991)
The first version, launched in arcades, utilized Capcom's CPS1 hardware. Players could choose one of eight characters to play, and after defeating the other seven opponents, four hidden bosses would appear.

Street Fighter 2: Champion Edition (March 1992)
The number of characters increased to 12. This version introduced the 2P feature, allowing two players to use the same character with different colors to fight against each other. This version was very popular and led to various derivative pirated versions appearing on the market.

Street Fighter 2: Turbo (December 1992)
Primarily aimed at fixing bugs related to pirated and hacked versions. Character moves were adjusted, such as adding a fireball move for Chun-Li and allowing Dhalsim to teleport. The overall game pace was significantly accelerated.

Street Fighter 2: The New Challengers (September 1993)
The hardware was updated to Capcom's CPS2, and the number of characters increased to 16. Character portraits and music were completely remade, and the game pace was consistent with the Champion Edition. Special moves underwent significant changes, such as Ryu's fireball turning into a flaming projectile and Ken's heavy Shoryuken setting opponents on fire. The game introduced a combo system and supported up to four arcade machines connected for an 8-player tournament. Based on the tournament results, players were divided into winners and losers brackets for 2-on-2 matches. There were a total of three rounds, ultimately determining the rankings of the eight players. Due to the high equipment requirements and the need for players to frequently change positions, this tournament format was not widely adopted at the time.

Super Street Fighter 2 Turbo (March 1994)
Known as Turbo outside Japan, this version further increased the game speed. It introduced a super meter and super combo system, making it the fastest version in the series. Players could adjust the speed within the game, and the popular character Akuma made his debut. If a player did not lose a single round before the final stage against M. Bison, Akuma would appear and defeat Bison with a single move, Shun Goku Satsu.

Hyper Street Fighter 2: The Anniversary Edition (2003)
To celebrate the 15th anniversary of Street Fighter, Capcom released this version for the PS2. Players could choose any character from the previous five versions, retaining their movesets. In January 2004, an arcade port was released, marking the first time the series moved from home consoles to arcades.

Street Fighter 2 Turbo HD Remix (November 2008)
Released on PS3 and Xbox 360, this version featured revamped graphics and music. Players could choose between the new or classic graphics while playing, and online play allowed for matches with players worldwide.

Ultra Street Fighter 2: The Final Challengers (May 2017)
Released on the Switch, this is the final version in the Street Fighter 2 series. It featured high-resolution graphics and introduced new character settings for Evil Ryu and Violent Ken.

Over 26 years, the official releases included eight versions along with various cross-platform ports. According to media reports, the series has generated at least $10 billion in revenue, solidifying its place as a classic in gaming history.
