Getting scammed in runescape and running your own scam-ring in runescape as a 13 year old taught me a lot about economics. It only has to happen to you a couple of times before you figure out not to do it again, and it does teach you a valuable lesson in economics... Never give a dickwad something up front in a trade, especially when that dickwad has anonymity and nothing at all prevents him from getting away with it.. You also learn to never make a trade that requires a commitment; never borrow money, and its more efficient to buy crappy items you can use now so you level up faster instead of buying super awesome expensive items that you can't even use yet - real world implication: when that 100,000 car breaks down, it's going to suck a whole lot more ass than when your 900 dollar "strictly a commuter" car breaks down
