I do think that Nintendo should make a concerted effort to bring back or make new RPG franchises. Imagine if Nintendo's consistent exclusive RPGs included Golden Sun and Advance Wars alongside Fire Emblem and Xenoblade. But, from what I understand, the developers of Golden Sun just aren't currently interested (don't know if Nintendo own the IP or not). 

Yeah, I agree.Xenoblade already grabbed the position of Nintendo flagship RPG in my opinion, but they honestly need more, in order to fill all possible genres, and also to try to grab a hold of a slice of the market.(all RPG genres I mean)

But I havent heard that part about Camelot not being interested on doing a new Golden Sun.And since I would guess that Nintendo owns Golden Sun, at least to some extent, they could simple assign another developer that would be interested in doing it.

I thought I heard that the head creators of the games weren't interested in making them after the DS titles, mainly due to sales ... could have sworn I saw that on a fan video about the future of Golden Sun (never played one myself but they look fun). So when I said that I didn't mean the entire studio, just the head creators, but yeah, I might be wrong on that anyways. 

Also apparently it is owned by Nintendo? https://trademark.trademarkia.com/golden-sun-77749719.html Kind of hard to read into this stuff though ... I don't know why it specifies Nintendo of America

Half Life 3?!

Nah it's probably the unannounced Retro Studios game.

What if Retro was working on a Half Life 3, and Valve was just ok with it?

Dreams....

I don't blame them since making Mario sports games is more efficient and brings in more revenue.  A new Golden Sun game would probably take Camelot three years to produce and sell 1-2m if things go right while they could probably make two Mario Sports games in four years and get 5m+ in sales.  Mario Tennis Aces alone might end up outselling the entire Golden Sun franchise.

I agree that the Mario Sports games are a lot safer bet but I don't look at it that way in regards to whether Golden Sun should make a comeback. Golden Sun 1 sold 1.76 million on GBA and Golden Sun 2 sold 1.22 million, that's pretty impressive for a new franchise on the GBA especially since the 2nd was released pretty late into the life of the console (not so late that it was irrelevant mind you, but still). After games like Fire Emblem Awakening and Xenoblade Chronicles 2, and after every Nintendo franchise has seen a huge increase on Switch ... comments like these are a bit head-scratching. They can always fill a niche in the Switch's library gap, and since Nintendo games generally don't have a big budget they don't need to have long development times. Although I think the problem is more so staff numbers ... Nintendo would probably just give it to another studio or hire more staff for Camelot. Either way, I don't think Nintendo will do it.

I might be mistaken, but weren't multiple insiders claiming Metroid Prime 4 was looking great and would be at the game awards show?

Another thing that should make fans go bananas is if Nintendo grabbed Squeenix by the balls and had them release Terranigma on the eShop, or even *gasp* make a sequel.

Most Americans have never heard of the game, let alone played it, and I'm skeptical it's widely remembered in Europe or Japan either.

Besides, Square will die before acknowledging Quintet's existence.
