I'm sorry but.. Whats the point of this thread? There's not much room for discussion when the OP has only two sentences and one reads "Nintendo doesn't make ads (or games...) like that anymore"
Without something more to discuss, it just sounds like the perfect place for someone to come in with the "Nintendo is casual now" rants that have been ruining the forums lately.
Now if we're going to be discussing how Nintendo marketing has changed over the years, in a positive tone, I'd expect a few more examples at the least, from across all generations. Until that happens, this thread doesn't have much merit.
I've added a GameBoy Commercial... which is eerily reminiscent of the DS' market sensibilities. Nintendo was selling to adults back in the 1990's, so don't think that the blue ocean is anything new.
The Perfect Dark Ad may imply that Nintendo was somehow "different" and has changed... but the GameBoy ad shows that... no, not really, Nintendo is still Nintendo and change-mongers should really turn the mirror on themselves.
I agree with the GB vs DS ads, Nintendo has always been trying to reach out to everyone, especially with the hand helds. Compare
the GameBoy ad you posted to
This DS (Brain Age) ad, both aimed at adults and not the normal "kids" that most people think all games are aimed for.
As far as the PD commercial goes, you gotta think of the times we lived in when those games came out. The N64 was up against the PS and Saturn that tried to push more 'mature' games, more so than Sega was with the Genesis the console era prior. Nintendo was trying break they're kid-friendly image with some games and the ads had to represent that, thus you get a more adult ad for a more adult game (not that T&A doesn't cater to anyone younger than the 18+ that M games are for hehe).
For the GC, Nintendo was still trying to break that image (and for those that say otherwise, may i remind you that GC was the home to the uncensored BMXXX game, not the PS2) and ads for mature games reflected that. Take
Resident Evil 4 for instance (NSFW by the way). Sure its not a Nintendo made game, but don't you think that if Nintendo wanted to be conservative enough, they'd keep this ad from airing? For those of you too lazy click, this RE4 ad is for the GC version of the game, and no PS2 logos are anywhere to be found.
Then take a look at this one for the
Wii Edition of the same game. This is much more of a trailer (at 2:00mins long) than a shot TV spot, but considering that Nintendo decided to take all their ads in one direction (gaming socially) with Wii games, you can see how much the behind the scenes stuff correlates to the type of ads they put out.
Oh, and who says Nintendo doesn't put out
some risque ads anymore?
