US President Barack Obama shakes hands with Polish Prime Minister Donald Tusk prior to a meeting in Warsaw, Poland, in 2011. AP/Alik Keplicz The popular role-playing game series "The Witcher" is beloved in Poland — so much so that back in 2011, the country's prime minister at the time Donald Tusk presented Obama with the collector's edition of "The Witcher 2: Assassins of Kings" to commemmorate his visit.

President Obama visited Poland again last June and had kind words to say about the game:

The last time I was here, Donald [Tusk] gave me a gift, the video game developed here in Poland that's won fans the world over, "The Witcher." I confess, I'm not very good at video games, but I've been told that it is a great example of Poland's place in the new global economy. And it's a tributre to the talents and work ethic of the Polish people as well as the wise stewardship of Polish leaders like prime minister Tusk.

If you're wondering why President Obama was given a copy of "The Witcher" in the first place, it's important to understand that "The Witcher" is not your average video game.

It's an incredible achievement for so many reasons.
