looks like GameSpot's taking a page from Joystiq's gaming book by trying a 12-hour marathon with a retail copy of
The Elder Scrolls IV: Oblivion for the 360 this Monday.
There will even be a live video feed of executive editor Greg Kasavin "driving" the game, but that will only be available to GameSpot subscribers. (Booo!) The event's currently scheduled for Monday, March 20, 6:00 PM-Tuesday, March 21, 6:00 AM PT.
Greg'll be "offering commentary about the experience as it transpires" via the picture-in-picture feed, but he won't be taking part in the concurrent subscriber chat room planned so as "to avoid any outside influences on his time spent evaluating the game." Well, good luck, Greg, and make sure to stay hydrated... 'cuz it's gonna be a long night.
