The deal will give Tencent two of the best-selling video games in the world as it recently bought out League of Legends producer Riot Games. That title is the world's top-selling PC game with $1.63 billion in revenue last year, much of that via controversial in-app purchases, rather than game sales. The company also owns stakes in Activision Blizzard, the maker of World of Warcraft, and Gears of War developer Epic Games.

Japan's Softbank is carrying over $80 billion in debt thanks in part to its $22 billion purchase of US carrier Sprint, which has been losing money for years. As a result, it's been divesting assets and plans to sell an $8 billion chunk of Alibaba, too. The deal will close by the end of September, 2016 barring any regulatory hurdles.
