Martin's book series that Game of Thrones was based on, would end the same way. No, the books are not going to end that way," Martin said. Over the years, Martin has been very open about the end of Game of Thrones and how the ending of his book series will be different. Clearly, overtaking Martin's book series and finishing before The Winds of Winter and A Dream of Spring were actually finished complicated matters. It's also just hard to wrap up a huge, expansive series like Game of Thrones the way that they tried to do it.
