i personally have never actually Platinumed a game due to how long it would take, i find that stuff to be really really bo-ring, which it actually is meant to be as a goal setter type thing, i'm not really into that, because although i know it's possible for me if i took the time, it's boring for me to do, it's like grinding in an RPG (except in those you usually have to to get strong enough to beat certain parts, some are exceptions)
