You can buy and sell actor or movie "stock" for virtual cash on the website Hollywood Stock Exchange (HSX). Starting in April the company plans on letting you turn those movie performance predictions into real dollars. HSX filed with the US Commodity Futures Trading Commission for approval as an active trading site in November 2008 and has just entered the final phase of regulatory review. Richard Jaycobs, president of HSX's parent company, said, "The number of people who visit movie theaters each year and form opinions about a film's success is in the tens of millions.

Last month we discussed news that Valve's upcoming shooter Left 4 Dead 2 had been denied classification in Australia, which meant the game could not be legally sold there. Now, after a series of edits which removed "considerable amounts of gore from gameplay," Australia's classification board has given the game an MA15+ rating. Their new report (PDF) says, "No wound detail is shown and the implicitly dead bodies and blood splatter disappear as they touch the ground. ... The board notes that the game no longer contains depictions of decapitation, dismemberment, wound detail or piles of dead bodies lying about the environment." The unmodified version of the game may still be approved, pending a review that concludes on October 22nd.
