User generated content will be created via the Xbox Live Silver Platform, where despite publishers being in charge of the monitoring the content (it will run through their servers), they still need Microsoft's approval to use it. At a Q&A session at Gamefest 2007, the annual Microsoft Game Technology Conference, Microsoft Software Design Engineer Zsolt Math was quizzed on Microsoft's stance when it comes to creating content and was asked whether a developer could construct a level editor on a PC and create levels that were playable on the Xbox 360."Even though nobody has done that, I would highly recommend that," said Mathe.
According to Epic Game's Mark Rein, Unreal Tournament III on the Xbox 360 will also feature fewer maps due to the limitations of the Xbox 360 hardware. "We'll compress some things. But you know, we may have fewer maps on the 360 version…Blu-Ray has definitely given us a lot of legroom."
