Diablo II was about gambling, hoping that you'd get lucky with a random drop and then playing again if you didn't. Diablo III is about investing.

Cynics would point out that Blizzard designed the game this way to push players toward their , where players can buy virtual items for real money and where Blizzard gets a cut of the profits on every transaction.

There's probably more than a little truth to that, but the game also has an auction house that operates using in-game gold rather than real currency and I recommend players take a look at it, because it's where the real game in Diablo III is going on right now.

Recently a player managed to defeat Act II of the game on Insanity, the game's highest difficultly level using gear bought off the auction house with only 200,000 in-game gold. To give you a sense of perspective, it takes a max level character about two hours to gain that much gold if they're dedicated to making gold quickly.
