This year's Electronic Entertainment Expo, or E3, kicks off in Los Angeles on Tuesday, June 10. With so many revisits to already successful franchises and a few originals with promise, it's shaping up to be a solid season for video game publishers. Here are five of the biggest games likely to headline next week: Ubisoft's Assassin's Creed Unity, Activision's Call of Duty: Advanced Warfare and Destiny, and Electronic Arts' The Sims 4 and Star Wars: Battlefront. Destiny is one of the most hotly anticipated and is on track to make histodry as the most expensive launch ever for a video game. Development, marketing and other costs could spike as high as $500 million.
