I only played like 3 hours of the GBA one but isn't Golden Sun a generic ass RPG?

What exactly is it that Nintendo needs to achieve? Why do they need to achieve it? How is this game vital to achieving what Nintendo needs to achieve?

No

What's special about it not-gameplay wise?

They need a shoot bang bang buff tits game to succeed because casuals love it

I've rarely hear the demand for a new Golden Sun so I'm not really sure if Nintendo needs this at all.

Nintendo only need to make the games that sell the most.

It is really hard to revive or get those classic IPs but didn't sell a lot. They need profits hence they won't make a lot of IPs which would sell around 100k WW or it is always depending on the dev cost/budget and what is the targeted number of copies that the game needs to sell. Easy for us gamers on what we want but Nintendo as a business, they need profits and will surely check which one would really sell. I know they have a few blunders on which IPs and what kind of spin off but we can't fault them every time as they aren't that of a big company that has a lot of dev teams.

I would really love to play those classic games and hope they'll revive it and have an HD sequel or so. Golden Sun seems a good example, but I'm not sure sales wise. I would love to have those Mario sports bundled into a single game, and have the wonderful Mario characters play it out, rather than splitting all those games.

I don't think Nintendo need another JRPG, but I guess the more the merrier .

Absolutely agree! In this case, the game you want also happens to be a game I think Nintendo needs. Not needs as in, "OMG it will save the Wii U/revitalize the 3ds!!" but just that it will strengthen an already diverse library and see the resurgence of an undervalued series. Unfortunately, Camelot is too busy making stuff like Mario Tennis to bother with niche titles like GS right now. I can't blame them, either. Wii U especially, needs revenue and Mario will bring in more revenue than Golden Sun.

I've only played the first GS, but it was an amazing game. Like you said, having a holy trinity of JRPGS would be a great pillar for Nintendo. It'd be amazing for Wii U (or 3DS) but I think they're going to play it safe until this gen is over. Hopefully, we'll see it land on NX?

Also, I do think Nintendo needs Metroid and F-zero more than Golden Sun since nothing else like either of them them exists and we already have a few JRPGS on Wii U and 3ds.
