10 richest video games developing companies of all time

5. Activision Blizzard

Activision merged with Vivendi Games back in 2008, and became Activision Blizzard, armed with combined powers leading to a number of franchises that made the conglomerate one of the major players in the industry. Their most famous franchise, the Call of Duty series, is perhaps the most popular, second only to Halo. The other big name by Activision Blizzard is World of Warcraft, the most famous role-playing game. No wonder it has a value of a whopping $4.85 billion.
