I've played Runescape on and off for eons, but something I've never been able to get my head around is how players knew the worth of an item before the Grand Exchange appeared. I made my first 100k at a point when I had loads of coal in the bank that I was going to smelt into steel stuff, smith, and finally sell to a General Store: the only way back then that I knew of making decent amounts of money. Obviously smithing was a hopelessly slow way of making money, but I would have carried on in a similar vein had it not been for this random guy who appeared in the bank one day, saying he'd buy coal for 200 gp each. I thought Christmas had come early. Thing is, though, that if he had offered 125 gp or something, I'd probably have sold the coal to him anyway because I had no idea what it was worth. I genuinely had no clue about pricing. I think with my earnings I bought a rune hatchet from someone for 30k, only to be told by one of the onlookers (after the deal was done >_>) that I'd been scammed. So how do people know what items are worth? Obviously their price in shops is a guideline, and the price to buy the ingredients is always going to be greater than the amount the items will fetch (excepting when the price has been pushed through the floor, like with maple logs), but what happens with items that sell in shops for less than people are prepared to pay for them -- party hats for instance, or crackers, masks and so on, even more mundane items like flax? How does a player without a vast amount of data about how many of each item there is, how many people want it and so on know the price of a given item? When GE fixed pricing goes out the window (as I'm sure its about to do soon ...) and the vast computing power of the Runescape team is gone, who says what items are worth?
