Welcome to Player Attack!
If you're looking to make a bit of pocket money doing something you love, you could do worse than spending a bit of time in the Diablo III Real Money Auction House. A dedicated player has reportedly earned more than US$10,000 in virtual item trading, including US$2,700 in just twelve days.
The anonymous person posted to social networking site Reddit, including screen-capped evidence of item trading and PayPal transactions. While we haven't seen proof of all $10,000, there's enough to convince many people that this person really is legit.
Under the label WishboneTheDog, the poster explains:
One of my favorite parts of gaming has been the economics of the item markets since I started trading in Neopets ten years ago. It is what first got me interested in economics, and I am now studying business at a good university. I hope to consult with game companies someday about balancing the economies of their games. (So Blizzard, if you read this, hit me up!)
Wishbone also claims to have never "botted, scammed, used any of the number of exploits, or cheated in any way whatsoever," in order to make the piles of cash. Instead, the gamer spent upwards of eight hours per day on the game in the first couple of months after launch. Since then, due to "IRL responsibilities" and study (Wishbone is a business student at college), that time's been cut back to a minimal amount per week.
Before this game, I never made any money off of what I did because it was against the rules.
In the Reddit "Ask Me (Almost) Anything" post, Wishbone goes into a little detail about how the approach works, where the idea came from, and things you can do if you're interested.
Be warned though - with Blizzard announcing just last week that more than 10 million people are playing Diablo III, it's no surprise that Wishbone has also observed the in-game seller economy is contracting, due to a saturation of supply. While it might be a viable option for some clever folk right now, there's no promises that the Real Money Auction House will continue to be a money spinner in the future.
