The thing I've seen in fiction that hasn't worked out in RPGs is an item that is tied to heredity or prophesy regarding the PCs.
Any magic item (or whatever) that depends on a PC having a certain lineage or fufilling a prophesy is almost doomed to fail. Think Excalibur. Think Elfstones or Sword of Shannara.
In my experience, even if you successfully get the item into the "destined" hands, it looks like favoritism to the other players. Campaign collapse almost inevitably follows.
Prophesies have similar results- the other players typically resent being "supporting cast" to the one you've chosen as the "Annointed One." Or annointed as the "Chosen One."
I did, however, manage to pull off a prophecy in a campaign once...but it turned out the PC everyone thought was THE ONE...wasn't. THAT worked out OK.
