Game of Thrones” prequel “House of the Dragon” had a fantastic premiere in August, introducing fans to an entirely different experience of Westeros — about 172 years before Daenerys Targaryen was born and 100 years after the Targaryens conquered the seven kingdoms. As expected, fans of the franchise — one of which I am — have begun to do their comparisons between the two. While both series belong to the same franchise, the difference in timelines already suggests that there will be significant differences between the two. This article looks at some of the major differences between “House of the Dragon” and “Game of Thrones,” as well as other info you need to know about the HBO series.

What is “House of the Dragon” About?

It’s a lot easier to put the pieces of “House of the Dragon” together if you saw the “Game of Thrones.” The two fantasy drama television series have their origin in the novel “A Song of Ice and Fire” by one of the creators of the series, George R. R. Martin. 

“House of the Dragon” chronicles the reign of House Targaryen over the seven kingdoms and the events that led to the “Dance of the Dragons” — the war of succession — which fans witnessed in “Game of Thrones” season five, episode nine. Since the premiere episode, “The Heirs of the Dragon” aired on August 21, 2022, there have been five other episodes.

  • Episode two — “The Rogue Prince”
  • Episode three — “Second of His Name”
  • Episode four — “King of the Narrow Sea”
  • Episode five — “We Light the Way”
  • Episode six — “The Princess and the Queen.” 

“House of the Dragon” was created by Ryan Condal and George R. R. Martin, both of whom deputizes as exec-producers alongside Ron Schmidt, Jocelyn Diaz, Sara Hess, Vince Gerardis, and Miguel Sapochnik. The HBO series was shot in four different locations — Portugal, the United Kingdom, Spain, and the United States. 

5 Differences Between “House of the Dragon” and “Game of Thrones”

Fans seem to agree on the fact that “House of the Dragon” is living up to the high standards set by the “Game of Thrones.” And while there are many obvious similarities — as is expected from a prequel — between “House of the Dragon” and the “Game of Thrones,” there are also quite a number of fascinating differences between the two. Below are some of the noticeable differences between “Game of Thrones” and “House of the Dragon.”

1. There are far more dragons:

In “Game of Thrones” we saw only three dragons — Viserion, Drogon, and Rhaegal, however in “House of the Dragon” there are about seventeen dragons. This is perhaps because the storyline of the latter is about a time when the Targaryens are at the height of their powers — just as their dragons. Although the dragons have been used sparingly thus far, fans can expect to see more of them in upcoming episodes.

2. There are also more Targaryens:

Fans only got to meet only four Targaryens properly in “Game of Thrones” — Viserys, Daenerys, Maester Aemon, and Aegon, aka Jon Snow — and only two were at the forefront. However, in contrast, there are more Targaryens in “House of the Dragons” and they are prominent and powerful unlike what we saw in “Game of Thrones.”

3. Concentration of power:

In “Game of Thrones” the Targaryens had become weak, hence a lot of houses/characters had the center stage. There was House Lannister and House Stark which were pretty much powerful, as well as House Baratheon and House Greyjoy. However, until this point in the storyline of “House of the Dragon” the Targaryens are the major focus with the other families playing second fiddle. They are still a proper dynasty unlike in “Game of Thrones” where they were now weak and their powers diminished. 

4. There are new houses:

In “House of the Dragon” we are getting to meet new houses that were never a feature in “Game of Thrones.” Houses like House Velaryon, House Hightower, House Cole, House Strong and House Westerling are all invited to the party. Albeit, we haven’t seen as much of them as we have seen of House Targaryen, they will surely play key roles as the series unfolds.

5. There are more digital effects:

Well, the world hasn’t stopped evolving since we had “Game of Thrones.” There’s been a lot of advancement in technology since then and you could easily spot some improved digital effects in this first season. Scenes like the face-off at Dragonstone appeared more electrifying and that’s nothing more than the awesomeness of improved digital technologies.
