I remember playing this game when I was only 12 and I had no experience at all with any of the SMT or Persona series before so blatantly I was terrified, dropped the game and said I'd never touch them again. Fast forward a decade and I played it, finished it, and loved it.
The only thing that I loathe about this game was the Snow Queen Quest, more so because I have absolutely no sense of direction and I kept getting lost. And let it be known that was the first time I'd ever cried out of frustration over a game (and let me tell you about the crushing disappointment I felt when crushed the final boss underfoot like she was nothing but a bug beneath my shoe, all of that and for an 'unstoppable force that will bring about nothing but darkness and cold', I didn't even feel triumphant when I beat her, all I felt was the stagnant cold apathy and swirls of rage over the fact that THIS is what I spent over 42 hours on and I didn't even get to enjoy it)
*and yes, to this day I still will not play this game again. Not even for the missing mirror parts.
