Server brings the demand, supply goes down and value goes up. You mentioned trying an item or a few being bought by the server up to a certain price to give some items more value. Doesn’t that idea serve the same intent?
(I probably explained what you said poorly; I’ll try again here. You mentioned on some other thread trying to have specific items on vshop automatically bought, bringing meebles into the economy, but giving items some more value. I liked this idea since it wouldn’t be a permanent change like a /warp shop sell sign, making it less likely to be abused for crazy quick profit by many)
