Well i for one think the FFXIV economy should not be control by the players, and should be moderate threw SE them selves to sustain a better economy in the game, leaving the choice of the price to players, was what devastated the FFxi economy in the first place.
leaving players to choose what the price was like telling a baby that he can sell his dollar lolly pop for 50k. the fluctuation of outrageous prices that end up with decade during the yrs is an example how people giving too much power over certain things can devastate an economy even in a game.
Actually, I think the things that hurt the FFXI economy were:
1) The auction house was the only easy place to actually buy and sell items. /bazaar was good for some things, but the AH made things easily available across zones and it was searchable.
2) Rather than show WHO is selling the item and how much they are asking for it (IE most other MMOs using the AH method), FFXI made you guess at the price and gave you the lowest priced instance of that item currently on the AH. Had they done it the other way around like the other MMOs, people could at least take a look and see that XxBEECHIPD00DxX is monopolizing beehive chips, beeswax,etc and perhaps he's also a gilseller and could not buy from him or any of his known mules. Not easy for everyone to know, sure, but it is more possible than with the FFXI AH method.
3) Things were either reasonably priced for the things players bought from NPCs/etc. Or they cost WAY TOO MUCH (Dynamis, etc.) which made no mid-ranged gil sinks to moderate the inflation a bit.
4) Hate to say it, but items didn't decay. Thus the market flooded. Desynthesis wasn't really worth it most of the time unless you were a goldsmith. If money changes hands more and goods actually LEAVE the game, then it's a lot better for the economy in general as the crafters can make more items and still sell them instead of just having this useless pile of stuff that's not selling because everyone that wants one already has one.
5) Gilsellers. Yeah, they really hurt the economy. You see, nothing in the game is WORTH any more as someone will actually pay for it. So if people are paying 50k for that 1gil lolipop, then they deserve to be scammed and that lolipop is now worth 50k to someone. If it's not worth that much to you, then don't buy it. It's not like someone is forcing you at gunpoint to buy it. With gilsellers, people just buy the gil, and they can now pay the 50k for the little trinket they want.
Hopefully SE will make things a little easier to get this time around. No more trying to kill 50 sheep for 1 piece of wool, 10 rabbits for 1 piece of rabbit meat, etc. Hopefully the NPC merchants will also keep items they have been sold and resell them until they run out so people can try to shop the NPCs for some bargains if they want. I remember doing that in Everquest constantly lol. For some reason I can't remember if FFXI merchants did that or not...
But to make everything in the game available on the merchant and price regulate would just run the whole point of player to player trade. That would make for a rather dull game especially if you like crafting.
Edit: I just wanted to add one more thing:
The other problem with FFXI's AH system was that when someone DID buy that lolipop for 50k gil, everyone else thought, "HEY! I can sell this for 50k gil too!" and thus the price stuck. Maybe in FFXIV they can give like an average price over say... a month or so so people can judge how much something has gone for? Perhaps if they were really ambitious it could even throw out any outliers (extremely high or low values) Edited, Apr 6th 2010 5:45am by shinichoco
