Yeah, I'm particularly thinking of Microsoft-Activision-Blizzard being able to jump ship with a Hearthstone 2, while Hasbro-Wizards of the Coast is probably now stuck paying Unity the money for Magic the Gathering Arena for at least a decade. (And even there, they are lucky, they were just mentioning that they were now thinking about going beyond the 1vs1, PvP focus of Arena just this summer !)
