Ok, first off gold has to be useful in some fashion to make it as the stable economic monetary value.
My proposal for a system that would bring uniqueness to the character's and for the implementation that gold could be viable has an economic source are twofold.
One, upon starting your character you are given a choice to pick one inventory item (No weapons for balance reasons). This item would be labeled Legendary and have its own unique color. However not a popular choice for many, but for balance sake it would have to be (EX in FFXI terms or Bound in WoW terms (god I hate wow >.> lmao)). Whatever the wording you would not be allowed to trade this item.
Upon character creation and selection of the armor piece of your choice you would get to name it, and as you level, it levels with you. This armor would have a level value also and experience points. Each level in order for you to add to its stats you would have to take it to an NPC and pay a gold fee in order to imbue any stats you wish onto the item. The item would have NO level cap. (I abhorr the idea of level caps in games). This would allow players who have capped out their character to progress even further once capped and give a reason for characters to have a main character.
Each level you attain with the armor piece would give you one stat point. Each attribute you wish to imbue onto the armor would have a pre-requisite stat point requirement. For example say you wanted +1 to all skills on your armor, it would require 5 stat points. Or if you wanted +25HP require 2 stat points, or you could balance it down so everything low tier was 1 stat point along the lines of +10 or +15HP / +10MP/ +1 Attribute or +2. Numbers are subject to change / testing and balance, however you get the general idea.
Also for example if you wanted to get added damage to a particular enemy type it would require for you to kill X number of creatures while wearing the armor. This would also give more replayability as characters would have to roam throughout the lands in order to get whatever bonus they would like.
These items would have a TEAL color for legendary. This item would be with you throughout your character life and would give a new and unique feel to your character knowing your the only character in the world with this armor and it allows you to critique your character to your playstyle and liking.
The possibilities of stats that you could imbue onto the item is limitless with your imagination.
The gold value for each increase of value would rise so it would give gold value along with decreasing the sale values of items and monster drops would be a good system to be put into place to stabilize the economy and give a good solid equilibrium to the value of items.
I also have another system in place that puts the emphasis of the game into the players hands. The bane of RPGs in todays world is that they are truely not unique and are pigeon-holed into roles. I will create another topic covering this and see your thoughts and will link it onto this once finished.
