OK, apart from the strategy games, I think a detective game where you have to move your gamepad around a scene crime would be awesome. The game could be Trauma Team 2, but let's go with a console sequel of Ace Attorney Investigations. It would include gameplay features of the DS games, improved cases with intricate stories. Don't think it would sell a lot, but I'd enjoy it and release it.

Actually, I think classic point and click games could work.

Just use the screen of the game to display an enlarged section of what we see on the TV, as a magnifying glass, and touch wherever you want with the stylus. And since point and click games don't need the second analog stick, it could be used to move the image displayed on the controller.

Also a good idea.

New IPs for the new Console are the best bet to have massive success

Just look at Ubisoft top 10 selling games list. It is all new IPs. Nothing from their past comes close to the new IPs they made in this current generation of games.

Grand Theft Auto sold like crazy on PS2... but not as much on X360/PS3 even though cost more to produce

I can give many more examples... but basically new/fresh will beat old/stagnant everytime they make equal quality product with equal level marketing support.

Good example. Seems like a very good fit as well as something with mass market potential! I like it! More importantly, I'd play it!

Regarding your question: I think part of the reason publishers are afraid of Nintendo consoles is they don't feel their ideas are very good fits for the environment or audience Nintendo serve. This was seen a lot this gen when the vast majority of games brought to Wii were essentially knock-offs of Nintendo games. It was as if developers literally didn't understand what Wii gamers wanted until Nintendo showed them.  Even when certain games or original IPs were brought over, many of them seemed to be a result of not fully understanding the audience. Examples of this are MadWorld, Zack & Wiki Little King's Story, Deadly Creatures and Crystal Bearers, games that had effort put into them but were misguided in one way or another and ultimately suffered for it in sales.

So while there were other reasons the Wii didn't get the support it deserved, this reason is something we have the power to influence. I believe if we share our ideas about how 3rd parties could find financial and creative success (at the same time) on Nintendo consoles, our ability to communicate our needs to them will improve. And just in case some of them are listening in, it may help them understand the audience better. I want 3rd parties to feel that many of their ideas are not only welcome on Wii U, they're in high demand! More importantly I want them to understand which ideas those are.

I like your premise! The Ace Attorney connection could work, in terms of popularity. Maybe making a Layton Detective Game would be even more popular.
 Also, great to see I'm not the only one who want's to get Wii U started with its right foot forward

^It's true

Ace attorney or Professor Layton are now very possible to make on wii U, just like scribblenauts.
Ace Attorney with the added DS features, obviously.

That would be fantastic.

That's the thing I talk about when I expect Wii U to do the same for home consoles as DS did for portables.

I must disagree with Zack & Wiki and Little King's Story.

The first was, and Capcom said it, an experiment to know what could they do with the controller. And while its sales were not spectacular, they weren't bad. And Little King's Story was a good game, at least that's what I heard as I couldn't find it anywhere. It was the Pikmin we never had on Wii.

But I agree with you on the others. Honestly, I don't even know how someone thought that a game were you play with a spider and a scorpion would sell.

Timesplitters! A wacky mode utilising the Upad's Dungeon Master feature would work very well.

Don't get me wrong, I loved both of those games. The fact is with minor changes they probably could have become much more popular, and that's why it pains me so much to see them wither away in obscurity. At least LKS is getting a sequel on Vita.

I think the main blunder the designers made on Zack & Wiki is punishing the player so harshly for making a mistake. For a game based around exploration and creativity, that really killed it for a lot of people. That was what I had in mind when I said the designers didn't fully understand the audience in that case. As an early Wii game, it should have been all about the joy of exploring the possibilities of the new controls, and in essence it still was. But forcing the player repeat long, slow sections over and over again was fundamentally a contradiction to this proposition. I can understand not wanting the game to be too easy, but it never felt like you were getting better at solving a lot of the puzzles as you went along. Especially towards the end, it didn't feel like you were developing any skill at understanding how to approach a given situation. That's bad design in my opinion.

Regarding LKS I haven't been able to put it in words yet, I just know there was something that game got wrong that made it unappealing to many gamers despite all its other good qualities. 

@gumby_trucker: I agree with you about Zack & Wiki. The last level pissed me off so much that I still have to finish the damn game!
