Microsoft’s Xbox video game division has announced new partnerships with Nintendo and chipmaker Nvidia. The moves come as Microsoft is trying to persuade European regulators to approve its planned $68.7 billion takeover of game publishing giant Activision Blizzard. A key audience for the announcements were the European Union antitrust regulators who held a closed-door meeting Tuesday with executives from Microsoft and some of their competitors, including Sony and Google. Microsoft announced a 10-year agreement with chipmaker Nvidia to bring Xbox games to Nvidia’s cloud gaming service. Microsoft also said it has now signed a similar deal with Nintendo, formalizing a commitment it revealed late last year.
