Inflation in MMOs with any kind of player economy is inevitable, and undesirable.
Inevitable, because every quest, every loot drop adds currency into the system, and the player economy passes it around rather than taking it out of game to NPCs.
Undesirable, because it results in new players being unable to meaningfully contribute to the player economy, and prices the out of the expected competence.
We need a way to take currency out of the economy.
We need, House Pharlani's latest venture. A Casino. Make it a large structure, a zone in itself. Make it a good nexus for differing areas so that people are encouraged to travel through it. (Perhaps an airship like structure with drop off stations in market, harbour and else where. Perhaps concentrate some Collector NPCs in the lobby or floor itself, or perhaps a boost on the usual tavern regen rates from the opulent surrounds)
We already have roulette and craps in the Phoenix tavern's back room all that we need is an incentive to use the casino. Thus, I propose differing floors each with games from Cannith made slots, to more active table games. Buy chips as you enter, use them directly, or play for more, and at the end of an evening redeem the chips for either items available nowhere else, or the coveted players grind for ever types. The important thingis to have a desirable way to remove cash from the economy, and that means offering something to those late game players with the most of it.
It would become a social hub, a place to catch up with guildies, look for groups, perhaps even get a few hints on quests you may have over looked from the barman. Thoughts any one?
