One element the PC version will have that the 360 version will not share is the TES Construction Set, which allows users to create or modify content in the game. Oblivion's apparently works very similar to Morrowind's in terms of the plug-in system, though I didn't get the chance to try it out myself. A few weeks ago, Microsoft's J Allard mentioned wanting to bring a "the open-source model" to games in respect to player created content, so I asked Hines if he foresaw content created with the TES Construction Set ever coming to Xbox 360. He pointed out that one problem with that is simply how open-ended the construction set is, with the possibility of diligent hackers using it as a way to find back doors into the 360. The decision of whether to allow that sort of content onto the system is Microsoft's. Still, he said, "If there's a point when it becomes an available option in the future, then we will be there on day one to work with them on doing it."
