Yes
@Franky Family , Really.
Nintendo's priorities orbit around their own creations. There's no chance they would buy the Halo franchise, and if they somehow ended up with it they would relegate it to retro content treatment. They'd hire out for someone to port the collection, and it might get remasters. There's a chance they'd hand it to a third party to make a new entry once every 10 years or so. It's not much different than Donkey Kong Country, which they never really even liked.
That's just being honest. They liked the technology that Rare came up with. It literally breathed new life into a fading 16-bit console that had fresh competition in the 32-bit Playstation. They weren't impressed with anything else about Donkey Kong Country, though. They've got some rather infamous quotes about the west's love of DKC. Even though they were publishing the games they saw them as competition to their first party offerings. lol
But anyway, they literally don't care for FPS games. They don't make them. Metroid Prime was a thing, and they don't bury it like they sort of do some other franchises probably because they realize it checks a box they have no desire to check themselves. There's enough interest there for an MP4. It won't sell great, but it's great fanfare.
If somehow Nintendo owned Halo, I think they would shop for someone in the west to make those games. They wouldn't ignore the value of the IP because it will obviously print some money. I just think they would not care about it much.
