Blizzard's Battle.net Balance boasts big business

Choo choo — the Blizzard Micotransactrain is leaving the station! Whether or not you're aboard with Blizzard's increasing fixation on monetizing all aspects of its games, this train is certainly picking up steam. Its next station is called Battle.net Balance, and with it comes a whole new paradigm for the Blizzard empire. (Many apologies for using the word "paradigm.")

In effect, Battle.net Balance is a virtual wallet where players can purchase — or "charge up" according to Blizzard's parlance — points to then spend on items and services in World of Warcraft, Diablo III, and elsewhere. Diablo III players who earn Battle.net currency in-game can save those points through the service to spend later. The system can also be used to pay for WoW gametime.

However, the system comes with an important caveat: Once you've converted real-world money into Battle.net Balance, there's no getting it back as cash. So if you've got plans to make a living playing Diablo III, you might want to think again (although "certain regions" will be able to cash out via PayPal).
