Creating a computer game phenomenon in Poland

Growing up in a country with no computers was not the easiest background for creating a global gaming phenomenon, but two school friends managed to do just that.

Marcin Iwinski and Michal Kicinski are the founders and co-owners of Polish games company CD Projekt.

Their Witcher series of games have sold more than seven million copies, and even US President Barack Obama is a fan.
