Follow-up to pay-to-play.

Microtransactions are bringing in 'hundreds of thousands of dollars' every month for Atari/Cryptic with Star Trek Online. If they release a new costume set... boom, income. A new star-ship design... income. And the work to profit ratio is stunning. They don't have to create whole new instances or release a new CD of content to generate revenue. They do everything small, simple and digital. No packaging, advertising, distribution. They simply announce a new in game goodie, set a small price and watch the fans dish out their money.

It's like Apps. Small, simple, but high-returns.
