I have been an active player of Runescape for quite a number of years. Over the years I have noticed the implementation of certain skills effecting the economy for a short period of time. The main one I remember is construction. I call this kind of skill a "sinkhole" skill as it essentially ONLY takes out money from the game. The addition of extreme potions in herblore did much of the same as well. It took resources out of the game. It did however indirectly add more wealth as it allowed for more bossing and quicker bossing.
The value of the gold coin in Runescape has declined a great deal in this game and I think I have some ideas that could possibly help siphon just a small amount of money from the game.
First idea - I have always received mixed reviews about this one. I suggest in some way making a fee for using the Grand Exchange to SELL an item. My idea (can however be tweaked) is that when you sell an item and get coins back a 5% fee is taken from the coins by the bankers. If you are someone who received the item as a drop one usually doesnt mind all too much as you have already gained the wealth. This could also help combat merchanting a little bit since the more you merchant (transactions you do) the more money is taken out of the game. Critics may say that people will stop using the Grand Exchange but the ease of selling in the G.E. is far too great for this small fee to outweigh the speed of selling an item in it. This fee would ONLY be done to sellers of an item and not to buyers. The percentage could be something different if desired I am just trying to throw the idea out there.
Second Idea - This actually came to me thinking about the barrows armour, torva, etc and the way that it degrades. I also was looking at how much the new death system has kind of made it really easy to get your gear/armour back with very little of a consequence. Dieing in this game unless in the wilderness does not carry the same effect it used to.
What I have thought of is a way to add a consequence to dieing which would be directly proportionate to what you die with.
Rough version - When you die all the stuff you LOSE goes into a coffin in your grave stone. When you get to your grave you do not have to pick up individual items but merely the coffin. However the coffin is locked and a fee must be paid to open it and get EVERYTHING out of it. The cost of this will be say 10% of the total worth of what is in the coffin. This would essentially create a punishment for dieing and also slightly take money out of the game. The items/coffin would be non-tradeable and the coffin could be banked. You can only open it if you can pay the full fee so you dont just get the really good gear or anything.
I feel that death in this game should mean something more. The fee is small for low levels and higher as you wear more expensive gear. The idea can be tweaked a bit but I do think the general idea is pretty nice. If there is any feedback please let me know.
Thanks for taking the time to read.
