I'm guessing she might be referring to all the people who thought 9 was "too kiddy" after 7-8. I personally loved it, and never really thought of it as an underrated game.
Yeah, that's similar to my case. I played it around the time it first came out and soon got stuck because I crafted shitty weapons. On my second run, just a few years ago, I actually finished the game and had a blast playing it. I didn't find crafting as hard as before, and realized that you can pretty much tear any boss a new one by paying attention and exploiting their weaknesses. I'm guessing many of the haters played it when they were younger, hated it, and never bothered to go back to it like you did.
