The share percentage depends
on the extent to which developers allow ads to be integrated into their games. Level I is a 10% share with few changes. Level II is a 20% share requiring modifications like localization, ratings by
the Entertainment Software Rating Board, and the inclusion of a "deluxe" game experience with 10 hours plus of Web-based play. Game play of that length used to be reserved for purchased games only.
Chris Early, studio manager for Microsoft's casual games division, says he believes the rev-share agreement will encourage developers to create richer gaming experiences. James Gwertzman, director of business development at competitor PopCap Games, gave the product a lukewarm reception: "It feels like this proposal was put together by someone with a spreadsheet operating in a vacuum; it simply doesn't take the market realities into account." In other words, the casual gaming market should remain casual. If people want richer gaming experiences, they'll get a PS3 or Xbox 360.
