I think when they add too much to one game it loses novelty honestly. Some things are cool for like a game here and there. Like deception had hara kiri and no other game had it.

Yeah I get what you mean but sometimes it gets boring doing the same finishers in MK11. Such as when I play as Johnny Cage I like his fatalities but it gets repetitive using them over and over again

Id rather they have 4 variants of fatality, multiple brutalities, and a few novelity ones

Fergality wouldn't make sense in a new game, though. It was based on Fergus McGovern from Probe who worked on the Genesis port of MKII, which is why it's exclusive to that version of MKII. Just leave it alone as a unique oddity of Mortal Kombat history. If it is brung back, it would literally make no sense, especially since Fergus McGovern is dead in real life (RIP)

I only included it because we hadn’t seen it on a while but I get why people wouldn’t want it brought back after his death

That's way too much work, but a great idea.
