- Level I: developer will be given ten percent of the ad revenue, no obligations necessary
- Level II: developer will earn 20 percent of the revenue, but their game must be submitted to the ESRB for a rating. The title must also provide a "deluxe experience" lasting at least 10 hours.
There's an added bonus for Microsoft concerning this business model, in that the more ESRB-rated games it has, the easier it will be for Windows Vista to properly filter content in tune to the Parental Control settings. The only outlet currently mentioned is MSN Games, but how long until this business permeates through Xbox Live Marketplace?
