ASOIAF is like a pyramid scheme of enjoyment.
You get in, slowly get frustrated as you understand that you won’t see the end, accept it, then you get to enjoy the next generation slowly getting frustrated.
We don’t have an ending, but we have this.
Isn’t it? I’m currently reading the saga and I would easily put the first book in the same category as the hunger games, and in fact the marketing blurb in my edition mentions both hunger games and enders game.
I’m told the rest of the series evolves into a more adult feeling in later books, but I definitely got some shonen manga / teenage adventure vibes from the first one - not that I don’t like it, I bought it expecting exactly that.
