Fairly sure the limiting publishers to so many games a year was NES only as SEGA came along with Genesis which was a more powerful and attractive platform without those restrictions. Konami's Ultra brand vanished after the NES era. NOA still had restrictions on religion and nudity of course. MK had sweat and no blood but after the feedback, MKII brought it back.SEGA forced Nintendo out of some of those aspects. Night Trap was possibly being ported to Nintendo PlayStation CD add on. When at the senate hearings Nintendo showed the game trying to pass the footage off as SEGA CD and saying this filth would never appear on a Nintendo system (lol Nintendo Switch says hi btw) but the quality was much better than SEGA CD.
