Van Buren was the codename given to what would have been Fallout 3, a role-playing video game that was being developed by Black Isle Studios before the parent company, Interplay Entertainment, went bankrupt. This resulted in the company shutting down Black Isle, which in turn laid off the PC development team on December 8, 2003, effectively cancelling the game. Several Black Isle staff members went on to form Obsidian Entertainment, and many themes, factions and characters of Van Buren were incorporated in Obsidian's Fallout: New Vegas, published by Bethesda Softworks in 2010.
