Notable Developers: 4A Games, GSC Game World

Notable Games: Metro 2033, S.T.A.L.K.E.R.

It makes sense that the two most notable developers in the Ukraine would both develop games featuring references to the Chernobyl Nuclear Power Plant disaster that so definitively shaped the culture of the country. The setting has been borrowed many times by many developers the world over, but it's 4A Games and GSC Game World that really manage to capture the desolation and hopelessness of a truly toxic area.
