Investors are disappointed there is no imminent takeover in the offing for the maker of Assassin’s Creed. Shares in Ubisoft Entertainment the developer behind the popular videogame franchise, fell more than 15% on Wednesday after Chinese internet giant Tencent Holdings Ltd. said it would increase its investment in the French company while agreeing to limit its holding, helping block a full Ubisoft takeover for now. Deal-making among videogame companies has surged in recent years, including Microsoft $75 billion deal earlier this year to buy Activision Blizzard That led analysts and investors to hope that other big tech and media companies would snap up the few big independent game developers that remain, like Ubisoft—pushing up their shares.
