The company was founded in 1995 by Sergiy Grygorovych (Serhiy Kostyantynovych Hryhorovych), who became chief executive officer (CEO). He came up with the company name and emblem in 1993, aged 15. "GSC" are the initials of his name in the transliteration "Grygorovych Sergiy Constantinovich". Later Grygorovych explained this decision: By 1996, the company employed fifteen people in a two-room apartment. Early employees included Grygorovych's younger brother, Evgeniy, and Andrew Prokhorov. The company was the first in Ukraine to translate video games into Russian, additionally creating multimedia CD-ROM encyclopedias.

In 1997 the company started developing its first video game, but difficulties in development led to its quick abandonment. In 1998, after the economic crisis in Russia, GSC reoriented to the Western market, developing real-time strategy games. GSC unsuccessfully tried to get a contract for the development of Warcraft 3 from Blizzard Entertainment. According to the CEO, they were rejected due to Blizzard's distrust of Grygorovych's youth. By the end of 1998, the company finished its debut commercial game, WarCraft 2000: Nuclear Epidemic. It was powered by its own engine, which was subsequently reused by Cossacks: European Wars. Nuclear Epidemic distinguished itself from other strategy games of the time with its increased unit size limits. At the beginning of 1999, it was released for free online. They began development on another project titled DoomCraft, which was shuttered six months later in favor of the development of Cossacks.

In 2001, GSC Game World released the real-time strategy game for Windows, Cossacks: European Wars. It was the first game that brought the company financial success and global recognition. Later that year, GSC Game World released the tactical first-person shooter Codename: Outbreak and an expansion for Cossacks named Cossacks: The Art of War. In the same year, GSC began developing a story-driven shooter based on the Stargate series concept and Aztec architecture. It was powered by a custom X-Ray Engine, which rendered high-quality images and supported many modern technologies. The project was titled Oblivion Lost. In 2002, the company released the combat hovercraft arcade racing game Hover Ace: Combat Racing Zone and another expansion to Cossacks called Cossacks: Back to War. At the end of that year, a new real-time strategy game named American Conquest was released. Also, in March 2002, after the GSC Game World company trip to the Chernobyl Exclusion Zone, the Oblivion Lost concept was wholly revised and used the Chernobyl disaster as a foundation. The game was called Stalker: Oblivion Lost, but soon the name changed to S.T.A.L.K.E.R.: Oblivion Lost, due to copyright complications with the word "Stalker". The rendering system was reworked. The game was scheduled to be released at the end of 2003. In 2003, the company released the addition American Conquest: Fight Back and the first-person shooter FireStarter. Also, the development of the first-person shooter S.T.A.L.K.E.R.: Oblivion Lost continued, and THQ became its publisher. By their recommendation, S.T.A.L.K.E.R.: Shadow of Chernobyl became the official name that got the first accurate release date – the middle of 2004. • Illustration — Logo of GSC World Publishing In 2004, GSC opened GSC World Publishing, a division that would publish GSC's games in countries of the Commonwealth of Independent States and in Europe. Together with Ubisoft on 20 November 2004, it published its own developed RTS game Alexander, the official game based on Oliver Stone's movie Alexander. The release of S.T.A.L.K.E.R.: Shadow of Chernobyl was postponed by THQ to 2005 due a transition to a new rendering process. In 2005, a sequel of the Cossacks strategy, Cossacks II: Napoleonic Wars, was released. In February 2005, the release of Shadow of Chernobyl was postponed indefinitely. In 2006, the company released an expansion for the Cossacks series titled Cossacks II: Battle for Europe, and a new real-time strategy role-playing game, Heroes of Annihilated Empires. The company released a statement that Shadow of Chernobyl should be released in the first quarter of 2007. At the beginning of the year, some GSC employees left the company to found 4A Games studio. On 20 March 2007, S.T.A.L.K.E.R.: Shadow of Chernobyl was officially released. On 24 March 2007, S.T.A.L.K.E.R. held the eighth position in the sales charts for various platforms, and the first position among PC games according to the rating of British organization ELSPA. On 12 February 2008, 950 thousand copies in the CIS and 700 thousand copies elsewhere in the world were sold, which made S.T.A.L.K.E.R.: Shadow of Chernobyl the most successful project of GSC Game World to date. The worldwide success of Shadow of Chernobyl pushed the company to develop its next project. On 5 December 2007, a mobile game, S.T.A.L.K.E.R. Mobile, was created by Qplaze in conjunction with GSC. On 22 August 2008, the stand-alone expansion S.T.A.L.K.E.R.: Clear Sky was released, a prequel for Shadow of Chernobyl. A sequel for Shadow of Chernobyl, S.T.A.L.K.E.R.: Call of Pripyat, was released on 2 October 2009, the third game in the series. In 2009, GSC began work on S.T.A.L.K.E.R. 2. The company officially announced the game on 13 August 2010. During development, the company shrank from 200 employees to 50. It had previously been the largest video game developer in Eastern Europe. Financial services company Ernst & Young named Grygorovych Ukraine's "entrepreneur of the year" in February 2011. On 9 December 2011, the Ukrainian News Agency, published a message with a statement from GSC Game World CEO Sergiy Grygorovych that the company had dissolved. Development of the S.T.A.L.K.E.R. 2 game was discontinued. Grygorovych stated that he did so for personal reasons. Studio spokesperson Valentine Yeltyshev said that the studio's financial situation played a minor role in the dissolution.

At the end of 2014, GSC Game World re-opened and announced that it was working on a new game. The company founder's brother Evgeniy Grygorovych (Evhen Hryhorovych) became its new CEO. In May 2015, the company announced Cossacks 3, a remake of the first Cossacks game, including "all its original gameplay". The game was released on 20 September 2016 on Steam, after which, the game was finalized and updated. On 15 May 2018, GSC re-announced S.T.A.L.K.E.R. 2: Heart of Chornobyl. The game was released on 20 November 2024, for Windows and the Xbox Series X/S. In 2020, Ukrainian businessman Maksym Krippa acquired a 40% stake in the company, and in 2023, he acquired an additional 42%.

When the 2022 Russian invasion of Ukraine began, GSC paused development on S.T.A.L.K.E.R. 2. The company used social media to urge fans and game journalists to donate to the Ukrainian Armed Forces and provided special accounts for donations. By May 2022, S.T.A.L.K.E.R. 2s development resumed after part of the team had been relocated to Prague, allowing them to continue working safely. One former GSC Game World developer, Volodymyr Yezhov, was killed in action near Bakhmut in December 2022. On 27 December 2022, a farewell ceremony for Yezhov was held in the Volodymyr Cathedral with the participation of a military guard, which was attended by many people. On 18 November 2025 the company was declared an "undesirable organization" in Russia.
