How thin has a competing/a fan serving brand have to stretch, to have a legit case of a shutdown? Bloodstained Curse of the Moon is = Castlevania 3. Bloodstained Ritual of the Night is SotN. Mighty nro 9 is Mega Man. I remember there was a court fight with Shouzou Kaga/Fire Emblem and Nintendo. Nintendo lost it. And the ruling made a case for all of these Japanese 'spiritual sequel' makers like IGA, Kojima, Inafune etc. to go and make it.
