FF16 was something like £15 on Amazon's Black Friday, that doesn't sound like a game that was a financial hit.
I'm replaying FF8 at the moment, just having reached the Ragnarök. It holds nostalgia for me in that the limited edition was the first thing I bought with my first ever paycheque (which I still have), but I don't recall ever replaying it since the days of the PS1. Whilst 7 and 9 are the better games, it's still a good game and the hate it's gotten over the years is overblown. Squall does start as an edgy boi but that doesn't last that long, even if it feels like his feelings for Rinoa go from 0-100 in an instant. The junction system is flawed and discourages you from using magic, but I do appreciate how they tried something different. Given how groundbreaking FF7 was following it was always a difficult task, and feels like a lot of the negativity comes from the fact they couldn't match that game's heights, and how Square never had the desire to return to that world.
