lately? lately? LATELY? The economy was worse than donkeys diarrhoea for the past 4 years now.
people wanting to buy low and sell high isnt a problem. that exist everywhere and its a normal way of market. thats why traders exist. Rune economy was ruined by cipsoft. the only runes bought form players now are sds, and even then most of them make it for ML and not money. Why the tibian economy is bad is explained by simple economys laws. supply and demand. we have low and ever lowering demand of items, especially the ones that arent "top item" because we have like 0 actual new players, just same guys starting new characters transferring their money to it. which means that with 0 demand the prices should be 0 (noones buying). however we have npcs that buy items, so the prices are slightly bellow npc price, because the only people selling to other players are those who haven't done the npc quests. The only thing i still see going is Plate legs, for 300 gp per unit. i remember buying them for 1200 gp per unit. the other huge factor in this economy downfall is oversupply. There are huge amount of botters looting huge amount of items and there are also huge amount of high level players that loot tons of items. not to mention the increased drop of items from new monsters. so the market is filled with tons and tons of knight legs, royal helmets, DSMs and so on. result is that prices fall in order to sell the amount. in this case, to npc prices. The only thing that saves this a bit is the items kept for house decoration, because those dont add to the supply.
However we also should have inflation, due to botters looting a lot of gold. and there are inflation on certain prices. however supply/demand is much stronger in this case than oversuply of gold, because gold is being spent on other things than the market (buying runes and fluids for example) thus it dissapears into npcs, so the inflation doesnt actually come to be, so prices still remain down.
Tl;dr - tibia economy is bull poo in all directions.
