I think you missunderstand something. I am Nintendo Fan and I dont care about third party anymore. Its mostly other people that whine about third party support. I mean sure it would be nice to have the third party support but that wont happen. Btw: 1 Game =/= support. Whining about a fanbase =/= support but thats another story.

I am pretty sure that after N64 and Gamecube well and Wii    alot of Nintendo fans are used to third party being absent. I am. Thats why I bought other systems starting with the Gamecube era but not for EA or Activison games for MORE games in general.

And I dont really care about third party anymore.  I mean they ignored the Nintendo fanbase with stupid excuses etc then promise something break their promises etc. they constantly do this.

They hide come out once per generation try a little bit and then give up   just to come back once per generation. They expect short term profit in a situation like this which is really dumb.

Why third party on Nintendo doesnt really work is this: 
They ignore Nintendo and constantly show N's userbase that third party is nothing you can count on/nothing you need. (the longer they are absent the harder it gets to convince Nintendo players that third party games are worth it) 

Then they try once to reach the nintendo fanbase and give up.
If other people are like me they WAIT and see if the third party game/port is good enough and then maybe buy the discounted game to see how it is or they wait for the second or third game in the series to come out. (to see if devs keep the quality level)

I am not willing to risk my 50-60 dollars anymore only to find out a game is shit thats why I wait for discounted games when it comes to third party games (but publishers automatically assume the game flopped which is not really true and then go back to ignore mode which automatically makes me hesistant to buy the next game again because if there is no constant support or the ports are handled by external studios there is no guaruantee the game will be good)
THIS IS STUPID!

They burned us so often that they NEED to convince us that the games are worth it!
( Yeah! Resident Evil for Wii!  Oh wait its a crappy rail shooter.....   Yeah! Dragon Quest for Wii!  oh wait its a crappy rail-rpg......  Yeah! Dead Space for Wii!  Oh wait its a crappy rail shooter.....   Stuff like this hurts the third party alot the games might be good but its not what people want! Or all those cheap 5 dollar production value games/shovelware....)

Thats the problem. Show me support that LASTS and then I might not be so scared and might actually buy a game. I mean the 60 dollars are worth more to me than to them since I dont earn 100000000 a month like  publishers do! 

Its not working because companies are stupid they want short term profit! With a userbase they abandoned. How should this work? They come out with cheap versions or shovelware and get their short term profit but at the same time establish themselves as crappy companies! The way to go would be  accept short term loss and establish quality brands/games (does not work with absence!!!!)  etc among the Nintendo userbase and then you can expect a steady increase of long term profit. This is how business works.

Lazyness prevents them from earning more money. Well whose fault is that? 

There is tons of ways to fix this problem  start with simple stuff like:

• Don't sell WiiU games for 70!!! while the PS360 version costs 60!!! THIS DOES NOT HELP!!!!!
• WiiU versions of games should (for a year or so) come out 2 weeks prior to the competitions consoles. People that dont care what platform the game is on but that want to be among the first to play it will buy the WiiU version.
• It makes no sense to bring out old games  or bring out games 1-2 week later to the new console (Call of Duty where most WiiU owners buy the other version anyway because their friends play other versions NOT WiiU FIX THIS WITH CROSS PLATFORM MULTIPLAYER!!!) or bring out single games and at the same time announce a trilogy for the competition. (Mass Effect).

P.S.
As mentioned above I started to buy other systems because there were not enough games on my Nintendo systems. BUT I almost only own exclusives for any console I have. I have like every first party game for PS2, PS3 and 360. I also have almost every second party game or third party exclusive. And if I have a "normal" third party games its only because the predecessor was an exclusive (like Dead or Alive 4/5)

This shows that my doubt about third party didnt disappear it found its way to my newer systems. Would be interesting to see how many former "Nintendo-only" players ignore games from EA/Activision etc... and bought their new consoles for MORE quality titles and not THIRD PARTY in general.

P.S. I also ignore almost every DLC game until it gets a GOTY edition (Borderlands 1, Batman Arkham City, Red Dead Redemption, GTA 4 etc.) or costs like $10 (Final Fantasy 13-2)


Flawed Summary:

1. Nintendo owners are partially scared to burn money because of third party quality.
2. Nintendo owners are not used to third party and need time to get used to them.
3. Nintendo owners cannot get used to third party because third party constantly disappears.
4. Nintendo owners might be the most "aware"/conservative video game consumers (no DLC games etc.)
5. Publishers should not focus on short term profit but on long term profit.
6. Publishers should constantly support and not jump ship after 1 fail they should establish themselves its in their own interest.
7. Publishers should do a Microsoft and accept a loss to gain access to a userbase/territory (MS doesnt give up Japan!)
8. Publishers should work not whine!
   
   

If anyore made it to the end. Thank you for reading this mess ;)

It's legitimately hard to produce a game that sells well with Nintendo fans (that let's face it, only buy long standing existent Nintendo franchises. Even Nintendo struggles with new core IPs).   Last gen there was an argument that it was worth the bother because of the costs of HD gaming.   This was somewhat valid and we saw various efforts, Just Dance, EA Sport Active, Madworld, Goldeneye, etc.  Some flew some didn't.   But WiiU is now HD and if you're going to try to win fickle casuals you can do that now much cheaper and easier on iOS/Android.   Why should anyone make any game for WiiU if it's not a guaranteed seller on Nintendo platforms?   WiiU will get Skylanders , Lego and Just Dance but not much else.   There's just no good business reason to bother.

Nintendo fans whine about 3rd party developers not supporting the Wii U and act like the 3rd party devs hate Nintendo and wants them to fail, which is not true at all.

If you love Nintendo so much why don't you support it by buying 3rd party games on the Wii U instead of getting them on different consoles? .

Every Nintendo fan who bought CoD or Assassin's Creed 3 on the PS3/Xbox360 should've bought those games on the Wii U, but that didn't happen and now you're blaming the developers for not wanting to make games on a console they won't get any money from.
