Diablo III has been a windfall for some players, including Reddit user WishboneTheDog, who posted of his transaction history and Paypal to prove his moneymaking prowess.
Aside from bragging, WishboneTheDog has alsoof Diablo III's population and economy. According to the blogger, the game's economy is rapidly slowing down, while players have stopped playing after they've completed the game.
He believes that once Blizzard updates the game with PvP, the economy will pick up again.
Blizzard gets a cut of all real-money Auction House sales, so it'll be interesting to see what the developer does to try to bolster sales, aside from adding PvP.
