i think what might make it really fun is to have truly unique items in the game.

Like, a series of special vanities that there is only 1 of them each. Period. If you have x version of this item, no one else will have it dropped.
But no ONE person can have more than one of these special items by way of game lock. That will make some things truly unique to have.

STS can release one unique item every 3-4 weeks or so and start the hardcore farming again ha ha
