I think a bit of marketing from Nintendo wouldn't go amiss. The mainstream population don't even know what Wii U is!

You clearly belong to the core audience, or the more enthusiastic, news seeking player, who cares about franchises and knows a lot about videogames. I don't think however that the label can be used to categorize games. I would believe that games are games, not core or casual. Some may attract some audiences more than others, in the sense of getting noticed. I think the problem comes when people label games as casual or core.

I think that Nintendo are hereby trying to recapture that lost audience, with more complex games and cannot do it by themselves, therefore resorting to third parties. However, core gamers will be difficult to attract when the other two HD consoles have secured greater support and the Wii U is relegated to second tier multiplatform products, late ports or a few exclusive games in more niche series. Big budget games of popular series will be skipping the Wii U, hence there will be no need for core gamers to upgrade to a new console that isn't getting such games.

Casual players at the same time, probably got tired of the same products and no disruptive games after 2009 which were new or captivating enough to make it into the headlines and keep the hype machine going on. Nintendo games were too few and in between, many of them extremely similar to their predecessors in the eyes of the casual cosnumer and not appealing at all to core gamers seeking for different, much richer experiences. (Not saying a game like Wii Sports won't catter to a core gamer, because it has a lot of challenge in it, however, other genres like action/adventure/RPG's demand higher attention and provide more immersive experiences to a player seeking it. Not to say that Wii Sports or Mario Kart may provide less fun, because they do provide fun and becoming an expert in such games is difficult and a feat a core gamer would go after, not just a guy trying to pass time and have some fun)

Let's just say that some genres are more appealing to a certain audience that other, but both audiences play all games, being their objectives somewhat different (mastering a games difficulty, completing the game 100% challenges and finding all secrets, becoming the best in multiplayer; vs. playing some rounds for fun, careless for details and not in extensive sessions) and of course these definitions are the extremes, there's obviously room for people in the middle, but most will be closer to one extreme than to the middle.

Nintendo had to move on from the Wii, they ran out of disruptive content for the casual audience. People were not talking about the Wii anymore like they were at the start of its life. They knew that without a new product they would be out of the race, which finally happened, as the Wii had provided most of what they could come about with. Consumers being now more tech savvy and knowledgeable about HD and being HD LCD TV's now in everyone's home, they had to make the upgrade. Of course, this time trying to be equally fair to both audiences and third parties who had dismissed Nintendo as a company to develop for, by giving them what they thought would be the perfect platform.

However they forgot that their image was already severely damaged among all of them, and that the battle would be difficult. They kept their plans secretely guarded and with their stubborn ways and greed, they thought that launching a console with just 1 big game (NSMBU, which in my opinion is a quick, last time endeavour) would have kept sales up for a long time. They did the same they did with the Wii, big game droughts based on hopes, instead of making sure that everyone would have something to look after. Same as with the 3DS, but one thought they'd have learnt the lesson, after 2 consecutive failures.

All in all, I think my given reasons for Nintendo's demise were quite close to what actually happened. Prolongued droughts of games, rehashed concepts, lack of new IP's and disruptive games, sending smaller projects to die, impression of a dire schedule due to an exaggerated degree of secrecy,  denial and ignoring of the core audience. They are just seeing the results now. They can turn things around, but not without a high cost, both monetary and brand related.

It's still too early! A lot of great games aren't out yet. Time for people to be patient. Remember how the 3DS was selling in the beginning. Too early people....

The Nintendo Direct that is due next month that is supposed to be focused on 3rd party titles is absolutely critical to the console..... Also, not sure about across the world but the television ads here in Australia are frankly embarrassing, I still can't believe how poorly Nintendo market their products.....

Nintendo have never marketed their products well here.  So nothing indifferent lol. 

Nintendo just made a system that no one really asked for, other than Nintendo's core fanbase that has to have any Nintendo console to play the next Mario/Zelda/DK/etc. (so lets put them aside).

No one wants another PS3/360 system. The PS3/360 themselves are like 6-7 years old. People want a big, clear upgrade if they are going to buy a new console, otherwise their hard earned cash is going elsewhere ... like a tablet or new phone.

Wii U controller is no Wiimote, does not generate the same excitement with casuals, takes gaming back to sitting on a couch and using 15 button controllers which is the anti-thesis of the Wii concept in the first place.

Nintendo Land is overly cartoony and has to be explained whereas Wii Sports was neutral enough for adults to get into it and straight forward to pick up and play.

Nintendo's milked Mario too hard the last 2-3 years.

System is too expensive, why pay $350 for a Wii U, when you can get a 360 or PS3 bundled with a game for cheaper and have a much larger library with better third party support and a slew of $20-$30 games. Batman: Arkham City GOTY Edition is $19.99 at my Best Buy for the 360. It's $59.99 on the Wii U.

Every Nintendo game fits both categories. Most of them have enough challenge for a core gamer to tackle entirely, but are friendly enough for a casual gamer to pick up, save for some games like Fire Emblem, where difficulty ramps up rapidly as the game progresses.

So I wouldn't label any game as casual or core. However, I can list the Nintendo games from 2010 onwards that may be more appealing for a casual gamer due to the genre the belong to and other aspects like single player game length or simplified controls, which I repeat, don't take the biggest challenges away from those seeking them:

- Wii Party
- Endless Ocean 2
- Wii Play: Motion
- FlingSmash
- PokePark Wii: Pikachu's Big Adventure
- Mario Sports Mix
- Fortune Street Wii
- Kirby's Epic Yarn
- Mario and Sonic at the 2012 Winter Olympics
- Mystery Case Files
- Mario Party 9
- Rhythm Heaven Fever
- PokePark 2

Ninty just let Wii die far too early, taking its name with it. Considering it was planning to take advantage of Wii's name also in its successor, letting it tarnish wasn't a good idea.

Or it could also be that people think Wii:genius=Wii U:gimmick.

And things are only going to get worse.....

Every 2nd thread we talk about it, open your eyes.
