It's not very hard to get a high tie ratio when you have a samll userbase ...

So your still telling me that games weren't the problem ? 

Actually, I think you're wrong. Smartphones are the most central explanation for why the handheld gaming industry as a whole has taken an absolutely massive nosedive in the matter of a single generational transition.

Many older players are not sure about carrying around so many devices simultaneously, while many younger ones are preoccupied with mobile games. The niche that handheld game devices used to fill is now filled by devices which do far more and are becoming practically first-world requisite. This greatly reduces the overall handheld market to core/persistent handheld gamers and a smaller but ongoing youth demographic.

There is also a small elderly phenomenon in Japan, but that's sort of negligible. 

You're naming much less proven problems for the 3DS. Marketing and time seem to have fixed the name confusion, the massive emergency price cut caused a 3DS sales spike, and innovation doesn't explain a lot. Meanwhile, the impact of smartphones is one that cannot be precisely measured but is quite qualitatively proven and quantitatively supported. This hit the Vita harder (it has more in common with a smartphone overall and has some of its own challenges), but it still hit handhelds en masse.

a variety of those things, combined.
I think mostly a lack of games especially when compared to the 3DS

No big AAA IP on it that's the only real reason why it fail

Yes, but other "failed" systems like the N-Gage (though its worth noting that ongoing Vita support makes it a non-failure, but rather an underperformer) have had low attach ratios. That high attach ratio is the result of the very core audience of the Vita (and audiences tend to get less core as they grow, as you implied), but it still requires a stable library of interesting and diverse titles. And indeed, the Vita offers that to its audience.

And yes, I am telling you that. Throwing more games at any system can help, but that doesn't explain its troubles. The Vita was troubled even when it had consistent and impressive high-profile game releases. It would still have that status quo, if not even more/faster releases, if not for troubled sales back then. The sales stopped (most of) the high profile games. Lack of high profile games did not cause the sales problem. Now that sales are too low to support many new high profile titles, it's a two-fold problem that is exercabiting.

So, in short, what we're really arguing is what the -root- problem is. And we know that the root problem is not games, because the Vita hit its struggles in the midst of a great flurry of titles and promises. Games depend on a platform even more than a platform depends on games, because the platform has to come first. If the platform doesn't do well after launch, the games will stop coming, creating a negative cyclical relationship. The Vita was not selling well in spite of its games, not because of them. 

If only Uncharted, Assassin's Creed, Call of Duty, Killzone, LittleBigPlanet, FIFA, etc. were big AAAs. :c

I seriously don't understand how people ever got it in their heads that this was the problem. It has that problem now because of lack of initial sales. But it had great AAA support at launch and still wasn't selling well in spite of that.

Okay. I just felt smartphones wasn't a good enough reason for the Vita's low sales, since the I thought the 3DS would've been affected by around the same amount, and didn't fully explain the gap between the 3DS and Vita.

I suppose that last sentence makes sense though.

Do you  think 5 games will change something,xbox1 and ps4 is getting at least 1 AAA game in a month

Severe lack of system selling games, overpriced memory cards, games that were a better fit for a big screen experience or had a superior PS3/PS4 version.

pc have the superior version it's didn't stop ps4 and x1 to sell well
