It seems that there is a new gaming empire on the rise. Activision who, thanks to its acquisition of Blizzard in 2008, now owns hit titles such as Call of Duty, Warcraft, StarCraft, Guitar Hero, Skylanders, and, of course, Destiny, is now adding one, or two, more to that list. It has just announced that it is acquiring King Digital Entertainment plc. While that name might not ring a bell, it's game might. It is the maker of Candy Crush Saga, the game that has a massive plummet of productivity worldwide.
