A game called "Sex" might not sell too well, but one called "Wii Sex" definitely would. Put it at the end of The Conduit and watch sales rise, rise...

Had they called Wii Fit "Fitness Training" or something along those lines, it would not be selling like it is. The same goes for Wii Sports Resort. A game called "Resort Sports" doesn't appeal to as many people. Taking it off Wii Play would be funny, as "Playing Around" sounds either weird or dirty depending on how you look at it...

Why has Mario Kart Wii become the fastest-selling Mario game ever? Because it has "Wii" in it's name. Had Mario Party 8 been called Mario Party Wii... you get the idea. The exceptions are Resident Evil 4: Wii Edition and Wii Music, the latter of which I expected to sell way better than it is.

You're making some flaws here.

Wii Fit didn't sell like it did just because it was called Wii Fit. It had brilliant marketing, and it was (is) a great piece of software. It also hits the Wii demographic spot on, and it was the first top-notch fitness game on Wii. The others can't get in because it took that position so clearly. If they hadn't called it Wii Fit, they would have had some other catchy name - Nintendo isn't EA (not a bash at EA quality, but they're horrible at naming games).

Mario Kart Wii had fantastic marketing. It was brilliant, and again - it hit the Wii demographic perfectly. It is also selling on a far bigger base than any previous MK (save for the handheld ones). Well, except for SMK, but it was the first in the series, so it doesn't get the same sales. Either way, the name Wii has nothing to do with it.

Resident Evil 4: Wii Edition doesn't benefit at all from being called Wii Edition. Does Wii Music? I don't know... Maybe, and probably more than Wii Fit and Mario Kart Wii.

Did Wii Play sell because it was called "Wii"? No, it sold because it was packed in

Same for Wii Sports.

Wii Sports Resort won't sell because it's called "Wii". It will sell because it is a title that every Wii owner owns, and that almost all of them love.

Not a single one of the "Wii" titles sold a lot more because they were called "Wii". Well, maybe Wii Music.

That's not to say a later title called "Wii" wouldn't get sales, because it would. Thanks to all of the above, "Wii" for games is a brandname. It's a sign of quality, like Mario. But none of the above, well, except maybe Wii Music, benefitted from that. They made the name, not the opposite.

Wii Chess.

Sorry, you are clearly making an unfounded opinion on the matter. You need to take other games that are clearly the same type of game with and without 'Wii' in the title to infer such a declaration.

Keep in mind any comparison must be between games of same type with a similar quality level.

And I agree with Oyvoyvoyv by the way.

There are a lot of games with "Wii" in the title.... compared to the small number of sucesses, there are more of them that fail, or at least don't have any clear sales advantage over games without.

Wii Sports is given away with the console in the West.... if it hadn't been an amazing game, you wouldn't even be asking this question.

Wii Play sells well because it is better than the 3rd party attempts at copying it, yet is 1/4 the price if you were going to buy a 2nd Wii remote anyway (seriously why wouldn't you want at least 1 extra remote)

Wii Fit is a clearly brilliant game, with brilliant marketing, part of that marketing does include putting the name Wii in the title, but calling it something else would not have hindered it's sales significantly.

Mario Kart Wii is selling because it is fucking amazing.

RE4? Well first of all it was a great game on the Cube and then PS2... it already has it's brand name recognition of "Resident Evil" what else would they have called it to make sure people know it is different to the older versions? And no the word "Wii" is not helping it.

Wii Music, as Oyv has said, is probably the only real example of this happening... the word "Wii" is helping it sell.... bad word of mouth from games journalist who went at it the wrong way is hindering it too though.... personally I think Wii Music is a mistake on the parts of both Nintendo and gaming journalism. In reality it is a niche product for those interested in the groundwork of making music, but it was advertised by Nintendo in the same vein as Wii Sports etc, ie a fun little family game... something it very much isn't. Meanwhile gaming journalism failed for the umpteenth time to understand what the Wii is about because they are trying to compare it's games to other games (in WMusics case, guitar hero)

Now try name another game that you think has sold better because of "Wii"

The only way to know for sure how much weight the name 'Wii' holds would be to release the same game two different names, and market them equally. Then we would know for sure.

I would agree that 'Wii' is currently the strongest brand in gaming. It is loaded with positive associations, and it has a very high recognition rate. Still, the products bearing the name must somehow fit the brand profile, or they will be ignored.

For that reason, Wii Sex would be a horrible product, that would not only sell badly, but also damage the Wii brand.

Wii fit would have sold well regardless but having wii in the name is a marketing move. Having your game have the name of the console infront of it is definitely a plus and makes it far easier to market as half the name already has significant mindshare.

By the way, I also disagre with the OP. If the audience would hate the first Wii-titled games, the latter ones would be damaged by it. 

Now that the "Wii series" turned out to be awesome on its own, as a new brand, future titles might get som help from it, but that is not the other way around.
