This, you don't know.
It also has to do with the popularity of the band at that time, I guess (1998 was probably not the time when one may have been urged to discover "this cool band", especially in the US, where Maiden were playing theaters). In 1992-1993, Maiden were actually on French national TV channels and radios (and this must count when you are 11-12 years old).
I had a feeling of being let down a few years after getting into the band too. I had built so much expectatiion for
The X Factor -especially since it was the first "new" release from my point of view, after two years of binging on the canon discography- that when I actually got to hear it...well, it made it difficult, though not impossible, to appreciate it right away.
