I played it for a few months just for the economics of it. This is how I learned what it means to 'corner the market'. I was trading water runes. It was a resource that had a niche usage for high-level wizards, when people wanted to sell it, (e.g. when they changed battle strategy), they usually wanted to sell them quickly, when they wanted to buy them, they also wanted to have them quickly. Also it was required for some more advanced spells so the people who bought them had been playing the game a while and had a lot of gold coins. Also because it was for such a niche use, substantial sales didn't occur very often. At one point, I had enough Runescape gold to buy up every offer that came up on the market for a low price, then I just waited for a desperate rich person to buy them all in bulk at a much higher price. Nobody else could provide them in bulk because I bought up all the smaller offers and big players who were engaged in high-stakes battles and had a lot of gold coins didn't want to run around buying up small amounts from a lot of different people. Eventually, I had enough gold coins to buy a rare purple partyhat which already cost like 50 million gps at that time. I quit the game when I went to university, sold the partyhat and gave away all the gps to some in-game friends. I regret doing that haha becuase now they're worth billions today and you can sell them for real money for thousands of dollars.
