Hmm, lets do this mathematically.

(PS3 plus 360) = HD.  

Wii = Wii.  

HD = 2.

 Wii = 1.  

HD > Wii ?

Third Party = 3.  

First Party = 1.  

3 > 1.  

Since HD = 2 and Wii = 1

2 is closer to 3.  So 3 = 2.

You can't psuedo-quote a line from Austin Powers 3 and expect people not to notice it!...

Wait, am I the first to notice?

They think a million seller on the HD systems is a hit, but a million seller on the Wii is a flop. Okay, that's just the gaming press and message board people, but it wouldn't surprise me if developers actually think this.

I have a different theory. Image and Power. When many 3rd party companies think about Wii, they think about the target audience, who is going to buy these games. Then they say "ok", Wii isn't the console of choice for "Red Dead: Redemption". We need a console where the target audience is 19-35 year olds. Ok PS3 and 360. It started that way and its continued to roll that way. Power. When you talk about how much power the Wii has compared to 360 and PS3, they're not the same. Multiplat games are easy to port between 360 and PS3 but when its time to port it on Wii, they must dumb down graphics etc. As far as the power theory goes though, I'm pretty sure most HD games could be ported to Wii and would look fine. 3rd parties like to bullshit. Image, well I'm not sure. Maybe Nintendo will pull a 3DS move and grab 3rd parties to develop for their next system. I mean think about it, ever since Wii, they've been slowly gaining 3rd party support.

Nintendo is focused on making games that will be talked about with a sense of nostalgia for years to come. Legend of Zelda: Ocarina of Time was in my opinion, inferior, to Legend of Zelda: A Link to the Past, but it was good enough for many of  my friends to speak fondly of it 10 years later.

Conversely, game developers and their publisher masters are focused on pumping out half-assed games because they have a quarterly bottom line to meet. Any game based off of a movie, Modern Warfare 2, Alan Wake, and on are clear examples where companies hype a bad product so that it sells a few million in the first month in order to appease individuals with the worldview of Bobby Kotick.

It is sad that the business side is messing with the gaming side. The gamers see this and that is why the Wii has sold twice as many more hardware units than PS3s. Then you would counter, what about all the casual games on the Wii?

What about them I say? A game is a game whether it be Tetris, Pong, Star Wars: Knights of the Old Republic, or Elder Scrolls: Daggerfall. Some people like to become hermits and spend  50 to 100 hours on their epic, obscure title, while they scoff at those who play games that they deem "casual" a tenth as much as they play their epic, obscure title. At the same time, those so called "casual" gamers view the "hardcore" gamers as having no life and looking like Cartman, Stan, and Kyle in the South Park episode "Make Love, Not Warcraft."

If you consider yourself a hardcore gamer, then do you view hardcore WoW raiders with reverence or do you view them as hopeless addicts who need to get out more?

The amount of fun one cannot get out of a game is not at all related to the  length, production costs, and development costs. Hell, I enjoy playing Tetris more than some Xbox 360 games whom are loaded with out of the way, pointless collectables just so that ex-WoW players such as myself will go neurotic in getting all of them. Games where the objective is simple and unobscured by collectables that have no relation to the story, I find more enjoyable most of the time.

I think it is due to multiple reasons, most being pointless:

Firstly, I think that for Western developers creating a game on the Wii/PSP/DS is seen as inferior as creating their game for the HD twins due to the power difference.  Therefore by creating a game on Wii/PSP/DS they think they are 'not doing their game justice'.

Secondly, I think they don't want to admit that they were initally wrong about the Wii's success.  They didn't expect the wii to take off as it did and therefore did not plan much software for it.  No that it has, they don't want a change of strategy.

I'd chalk it up to two other things: 1) Not understanding why games sell in the first place, and 2) Thinking throwing money at a game is more important than good design.

1. They think games they like don't sell on the Wii, but perhaps why they like games that sell on the HD systems are not the reason they sell. Take Chinatown Wars, which was a DS game, but still fits. They create a mutant game that doesn't even capture the feel of the top-down games, and especially not the 3D games that made the series a firt tier franchise. So thinking that running around a 3D world wreaking havok is not the reason that the series became a hit, and thinking just being called "Grand Theft Auto" and getting good reviews (which are also not due to being games in a 3D world wreaking havok) is a sign of not understaning why games sell.

2. A lot of HD games have good design, but it seems the developers think those are just things to throw in, and the graphics are what make the game. So if something limits the graphics, they don't know what to do. They spend more time on the graphics and less on design, which gives us rail shooters that slow down the action and try to show all the detail they put in.

So I believe a lot of developers are as dumb as this thread is implying, just in many varied ways.

So, has anybody even bother to imform the guy of the incorrect number?

^No need to bother.  Industry commentators, analysts and executives finalized their divorce with reality some time ago.  Reintroducing them to reality now is sort of like explaining music to a deaf man.

Wii didn't getr good third party support for three reasons:

The first reason was that everybody saw the Wii falling to a distant third place this generation.  As such, they figured that they would make more money by supporting the two HD consoles. 

The second reason is that once developers saw that the Wii was  doing well, they decided to support it with the wrong types of games.  They had second and third string development teams make "casual" games for some easy money.  The games didn't sell, and developers were out of money.

Third, they put all of their main franchises on the HD systems.  So now, they are stuck on those systems as that is where all of their customers are.  If they switched over to the Wii now, they'd just sell less than they would on the HD systems since they would be effectively fragmenting their customer base.  Someone who bought a PS3 for Metal Gear probably isn't going to buy a Wii to play the next installment of Metal Gear, for example.

So, third party support is limited to spin-offs of main franchises and new expanded audience games.  Ubisoft got a smash hit with Just Dance on Wii for example, but Assasin's Creed will never sell that well on Wii since most all of the AC customers are on 360 and PS3.  Wii won't get the next installment of FF, and offshoots like Crystal Chronicles will continue to do relatively poorly.
