Both EA and Activision blizzard are safe bets at the moment. Between them they own the Star Wars license for games (EA), FIFA, Madden, NBA (EA) Call of duty (ATVI) World of Warcraft (ATVI) and still the cash cow which is Heartstone and the upcoming Diablo Mobile game which love or hate it will make billions in the Asian markets. Not forgetting that Tencent own a large chunk of Activision Blizzard, which could cause issues for those who are vary of supporting Chinese trade.
They maybe the two most hated game distributors among gamers, but they still keep on making monthly battle passes and the same games each year and people still keep on buying them. Most of these games have moved on from loot boxes to more elaborate seasons passes, so any new law is unlikely to cause disruption.
