Guests of the Event

A legendary Finnish computer game developer, trained as a computer scientist, who routinely programs systems for power plants. At just 19, during a break from military service, he wrote a game in Turbo Pascal that forever changed the world of virtual sports – Deluxe Ski Jump (DSJ).

His proprietary physics engine and brilliant analog mouse controls made DSJ a gigantic, multi-generational phenomenon. The game gained a unique, almost cult status in Poland, where millions of players enjoyed it during the "Małyszomania" era. To this day, Polish fans and modders constitute approximately 90% of the series' community. Jussi continues to develop his iconic project – porting the classic DSJ to mobile systems, and in the latest versions, he hid his own face as an Easter egg.
