So we're all well aware that Nintendo have a selection of really awesome IPs (Metroid, Fire-Emblem, Pikmin, Kirby, and now Xenoblade) that have had incredible titles fall outside the public consciousness. I will admit I am hopeful for Awakening being able to mark the beginning of possible future for Fire-Emblem to join the other group, but I am curious what people think would mark the opportunity for a franchise to move between these too groups.

Lets focus on upward mobility, how would you achieve mainstream interest. You can't change the nature of Nintendo's approach to console design, but you have unlimited marketing funds and get to talk to the individual lead designers for each project. For convienence, lets assume that all these games were pulling constant 88s<->92s on Metacritic... 

Ready, set, strategize... 

Nintendo's Youtube Creators Program

Just make a lot of GOOD ads! That's it. Really. Spend enough money on GOOD advertising. But I think you'll just have to accept that some of Nintendo's games are quite niche and won't appeal to a larger market.

Movies and TV Shows.

I want them on the BUSSES I ride to school!!!!! Please Nintendo!!!

I only saw and hooped on the one with the Legend of zelda a link between worlds =D I keep seeing the PS4 one.

disney partnership.
let them make movies of nintendo ips.

everyone knows elsa, but no one knows rosalina.

This and they also need sacrificing a lot of money for advertisement. And cheapest way is utilizing blog or Youtube.

Put

FROM THE CREATORS OF
Zelda/Pokemon/Mario/Smash/Animal Crossing games

on the box :)


No seriously Nintendo should put

NINTENDO PRESENTS
"INSERT GAME TITLE"

on all the covers.

So people do know its a Nintendo game.
(they do have to mke the games first tho obviously. Metroid where are you?)


Other than that do a reallife NINTENDOLAND.
Bought metroid on WiiU? Get all the Metroid themed merchandise for 50% off (once per item per customer)
something like this.

Some would really benefit from tie-in cartoons/anime

Fire Emblem would get a proper 15+ anime, think Air Gear in terms of target audience. Star Fox and Kid Icarus would both get cartoons, think Bucky O'Hare/Biker Mice from mars for style, aimed at 10-13 year olds. Kirby and Yoshi would get cartoons aimed at the under 12s. All of them aside from Fire Emblem would be outsourced/joint venture with Disney/Cartoon Network. Fire Emblem would need to go to an adult audience.

More TV advertising is a must.

I'd also look at the possibility of comic books as a way of promoting Star Fox, Kid Icarus and Kirby. Same age ranges as before. The key element is to generate the sort of interest in those IP as our generation had in Pokémon, Transformers, TMNT etc.

The characters and world of Kid Icarus and Star Fox would really appeal to that male tween demographic, but they need exposure to it. TV shows, with accompanying comics, toys and merch, would drive the interest in that brand. Look at something like Adventure Time or Minecraft for a reference. These have really captured children's imaginations in a way that Nintendo's properties haven't in a while.

Also, in the OP it gives me unlimited marketing dollar...

Theme park.

Or rather, work with Disney in order to add in a Nintendo Land section in a several of their themeparks. They'd have a Peach's Castle, Yoshi Dodgems etc etc. A few roller coasters based on adult franchises, such as Zelda and Fire Emblem, and then smaller attractions aimed at the relevant age groups. Again, this would be about putting the branding and the properties into people's consciousness.

The key thing is to ensure that there is saturation of the key demographics for each property. Fire Emblem and Xenoblade need to be strictly older teens/adults. Kid Icarus, Star Fox and Luigis Mansion etc should be aimed at the under 14s. and Kirby and Yoshi should be aimed at the under 10s.

More crossover games like Smash Bros. Before 2003 I was mostly a Playstation gamer, I came to know many of the lesser known Nintendo IPs thanks to smash bros melee.
Expand mario maker, and add assets from other Nintendo frachises. Rather than making a Mario themed party game, use the same format but add more franchises. ( for example I think it would be the great idea to use NES remix challages as party minigames).Add themed chatacters and courses on Mario Kart etc. Etc.
