The top eight players will receive various items that touch on Rohrer's personal history. Sixth through eighth place will receive a $50 gift card to Custom Cartridge, a guns and ammunition store Rohrer visited, second through fifth place will receive an anti-burglary device known as a Door Devil, while first place gets a dog club - "the club that started it all," as Rohrer describes it. Each of the top eight players will also get to have their favorite in-game painting become a real-life, 20x20" giclee-printed canvas.
Players have until 5 p.m. Pacific on Monday, January 27 to amass their virtual fortune, at which point Rohrer will take a snapshot of the server database. The top eight players will be ranked according to their house value, so long as that house is on the public house list, and not kept private.
