Witcher 2, The - Assassins of Kings Cheats
the main character is named Geralt of Rivia some kind of warrior/wizard.
Sadly, only two of his books have been translated into English yet, The Last Wish and Blood of Elves
Sorry, but just
Game of Thrones is based on A Song of Ice and Fire.
The Witcher is based on the eponymous book series, which as was previously mentioned, only has two installments in the english language so far. I prefer the original Polish versions, but seeing as I don't fluently speak it, meh. Still worth reading, however. The games take place after the series ends.
There was a movie, which was, in turn, a cut down version of the TV series based on the books. They're not good. At all.
Only Geralt of Rivia can help save the Starks now. I smell a profitable crossover in the making.
