Here's a few standouts that spring to mind:
Zeno Clash: Developed by Ace Team of Chile.

The Void Developed by Ice-Pick Lodge of Russia

Minecraft Developed by Mojang of Sweden

I don't know enough about the respective cultures that these games come from to know if the games are influenced by their nations of origin, but each one has a very unique feel to it. Zeno Clash has a primitive brutalness to it's gorgeous fantasy world. The Void is dark and bleak with a cold beauty that emerges out of its isolated landscapes. Minecraft is hearty and joyful with the endless promise of creativity and the constant threat of destruction. Perhaps it's partly due to their cultural origins, perhaps not, but each of these games presents a unique and compelling world that is not like what we traditionally see in videogames.
