I bought P3FES one summer many years ago, and I was so addicted to it that it literally changed my sleeping pattern because I would rather play it then fall asleep. I went to bed at 9-10 in the morning that summer. Then, all of a sudden, I just stopped for a long time. I got back to it like a year and a half later to finish off the Journey. Up to this day, I haven`t finished the Answer.
I found Persona 4 in my university library a couple months ago (I know my university lets us check out games, it`s awesome), and I took it home immediately. The same thing happened where I played a ton of it for like a month, but then I was kinda burnt out. I'll probably check it out again later to see if I can finally finish the goddamn thing.
