GSC Game World just marked 30 years in the game industry, and the Ukrainian studio’s journey from multimedia encyclopedias to one of Eastern Europe’s most respected developers is nothing short of remarkable. The team dropped an anniversary video on November 24, 2025, thanking fans for walking alongside them through three decades of world-building.
From Kyiv to the World
Sergiy Grygorovych founded GSC Game World in Kyiv, Ukraine, on November 25, 1995. The company didn’t start with games, though. For the first two years, GSC focused on producing multimedia encyclopedias and edutainment software that gained popularity across Ukraine and Russia. The shift to game development came in 1997, setting the stage for what would become one of the region’s most successful studios.
The name GSC comes from the founder’s initials. What started as a small operation in Kyiv grew into the largest video game developer in Eastern Europe at its peak, employing over 200 people. Today, the team operates from multiple locations, including Prague, after circumstances forced them to adapt their operations.
The Games That Built a Legacy
GSC Game World’s first major hit came in 2001 with Cossacks: European Wars, a real-time strategy game that sold over five million copies worldwide along with its two add-ons. The Cossacks series put the studio on the map and proved that Ukrainian developers could compete globally. The success of Cossacks led to sequels including Cossacks 2: Napoleonic Wars in 2005 and Cossacks 2: Battle for Europe in 2006.
But the STALKER series is what truly defined GSC Game World’s identity. After a company trip to the Chernobyl Exclusion Zone in March 2002, the team completely revised their Oblivion Lost concept and created something unprecedented. STALKER: Shadow of Chernobyl launched in 2007 after years of development, mixing first-person shooter mechanics with survival horror elements and RPG systems in a way no other game had attempted.
The STALKER trilogy expanded with Clear Sky in 2008 and Call of Pripyat in 2009. Each game built on the atmospheric, dangerous world of the Zone where reality bends and survival demands constant vigilance. The series cultivated a dedicated fanbase that kept the games alive through mods and community content for over a decade.

Surviving Against the Odds
GSC Game World’s story took a dramatic turn when political conflict escalated in Ukraine. The studio, led by Ievgen Grygorovych and his wife Mariia, faced the impossible task of continuing work on STALKER 2 while ensuring their team’s safety. Mariia organized an evacuation operation that moved many employees from Ukraine to Budapest, navigating blocked roads, border crossings on foot, and the chaos of a country at war.
Despite these challenges, the team pushed forward. STALKER 2: Heart of Chornobyl launched on November 20, 2024, for Xbox Series consoles and PC, selling over one million copies. The PlayStation 5 version followed exactly one year later on November 20, 2025. The game’s success proved that even in the darkest circumstances, GSC Game World refused to give up on the world they’d been building for years.
Anniversary Celebrations
For the 30th anniversary, GSC Game World released a short video reflecting on their journey. The message was simple but powerful: “We create worlds. And you are the ones who make them breathe. There’s never been ‘we’ and ‘you’ – only us, together.” The studio emphasized that this isn’t an ending but just the beginning of their next chapter.

Whether you want to experience the STALKER trilogy before diving into the sequel or explore the historical warfare of the Cossacks series, the timing couldn’t be better to catch up on three decades of game development.
