Jeffrey Yolahem owes his career to the video game “The Prince of Persia.” Growing up in Santa Fe, he loved the game so much he would write additional scripts and stories for the historical adventure just for fun, and as an undergraduate at Yale University, he sought out Jordan Mechner, the game’s creator, for advice about what courses he should take to pursue a career in video game script writing. (The answer? Screenwriting and architecture classes, to better understand the level designs of video games.)

Yolahem, 26, is now the lead writer of the newly released video game “Assassin’s Creed Brotherhood.” ‘Brotherhood’ is the latest installment of French video game publisher Ubisoft’s “Assassin’s Creed” franchise, which has sold over 19 million units worldwide. The title continues the adventures of modern-day bartender Desmond Miles and Renaissance-era assassin Ezio Auditore da Firenze, whose memories Desmond is able to access through a machine called the Animus. As Ezio, single players must recruit and lead a ‘brotherhood’ of men to fight against the powerful Templar Order and take back the crumbling city of Rome.
