How did things necessarily become "rare" on the original VMK? And how do we implement the same system (unlike OVMK) into this?
When the beta period in VMK ended, certain items were no longer available for players to buy (such as green flips, specific colors of furniture, etc). Those items became known as "beta," which is certainly rare.
Other items were only sold for a short period of time, so limited numbers of those items were sold. Over time, those became rare because of the influx of players.
Other items were called rare, but weren't. Those stayed "rare" for some people because the demand was always high for them. The Pirate Quest items are a great example of that - at one point they were truly rare because they weren't available and only a small number of people own them. When they became available from Disney Parks cards...sold with pins, then the rarity of those items was significantly reduced. However, because of their demand, they were usually called "rare" by players.
On VMK, the term "rare" came to mean that an item had a high value. The term "beta" came to mean that that items was both rare and in high demand.
