It may be the largest entertainment production in history. More than 800 people on four continents have spent six years and nearly $200 million creating it. The story runs 1,600 hours, with hundreds of additional hours still being written. Nearly 1,000 actors have recorded dialogue for 4,000 characters in three languages. The narrative is so huge that writers created a 1,000-page “bible” to keep the details straight, and the director recently asked a colleague not to spoil moments he hadn’t yet seen. It’s not a movie or a TV series. It’s Star Wars: The Old Republic, the most expensive, ambitious and riskiest video game ever produced.
