I've played this game at least 5 times back in the 90s in Vietnam when it first came out in Japanese even though I didn't understand a word of it. I didn't even know what name it called in English, I was just a little kid back then. I was still be able to work out a few simple calculations, pairing system, forged 100 kills weapons and most of the secret events, no in-depth calculation nor love growth like you guys have today but I absolutely love it.
20 years later and here I am, found the English name of it, found this dedicated forum, English translation patch, emulator and started play it again. It's like new to me as I forgot all of events, secret or not. I get to end of Chapter 8 now and I understand the story line a lot clearer compare to before. I plan to re-run it to get AAAA ranking.
Looking at my XBone and PS4 gathering dust as I hardly play them even though there are so many modern games with better graphic, I guess your best childhood games will follow you forever.
