Dragon Quest Reimagined - Heroic Horder.

If I understand correctly, to achieve this, I have to collect all 476 items in the game. There is no list in the game where I can see exactly what I'm missing. There is also no video on the internet for this. Are the developers mentally challenged to demand such degenerate garbage? How can they have so little respect for their customers and their time? Thats insane. I will pass on the platinum.
