Where are those old days when you had a suspicious item with no use in a Final Fantasy. Later on you realise it is the Best because after used all or gathered some others of them, you will get ultimate equipment or so...
Dont you remember the Parts to collect for "Ribbon"?
The Thing was: Many players thrown it away because there are just some hints in description but nothing more.

Or the old times when having 99 of a item triggers a special attack (example Phoenix)
