Why on earth would you stick with the series so long when the majority of the games are dungeons, ever since the original?
Because I love the characters, the stories, the lore, the worlds, the items, the gameplay, the music and the art styles.
I was playing Zelda long before I understood the concept of video games. I'd listen to the music and wonder why the screen would change sometimes when the little man sometimes moved.
LoZ and AoL got me through years of abuse long before I knew what they were.
Years later ALttP would change my life and introduce me to video games as a story telling medium when I realised that it was part of the series of games that had helped me through so much.
So I kept playing, wanting to meet more characters and learn about the ever changing world I'd spent my earliest years in and now I cant bring myself to put the series down, no matter how crap it gets or how many dungeons it makes me do.
