Wait is it? PSV has been on the market for 10 months now and it only has 1 game with a metascore of 90+. 3DS has 4 in 20 months, which is on average 1 every 5 months, or twice as fast as PSV.

In the future, I only see this shifting even furtur in Nintendo's favor with games like Dragon Quest VII, Fire Emblem, rumored Donkey Kong Land Returns, Monster Hunter 4, and Bravery Default coming along.

Your list is incomplete, just look at the Most Wanted section if you want ot check for all the games. I bolded what I added.

So 3 exclusive Vita games, a port, and 3 enhanced remakes.

and 12 exclusive 3DS games, a port, and an enchanced remake.

This kinda favors 3DS....just a bit.

Simple more powerful system so people can make better games without needing to include any 3d

Ok, let me help you:

Nintendo's own software is powerful indeed but it's in no way choking the life out of 3rd party games at all.  PLvsAA sold a mere 130k it's first week but I think it's Layton is holding PLvsAA back.  We'll know soon enough once the next AA5 releases. The most plausible explanation is series fatigue and isn't attributable to Nintendo's software "choking" it like you said.  Your Resident Evil comparison isn't a good example.  The RE franchise is the opposite of MoHun, where iterations perform better on handheld than on console and vise-versa.  Same thing for the DS and Vita Call of Duty games, they perform much better on console than handheld.  LBP is another example.  The PS3 had a bunch of Resident Evil games and the base is already there.  The 3DS had a spinoff and then a main line game.  Sales increased from Mercenaries to Revelations, and comparing a console RE to a handheld RE isn't really helping you.  Just because 3rd party games don't meet your arbitrary standards doesn't mean they were bad investments.  Marvelous went on record saying Rune Factory 4 was the highest selling game in the series at just 150k units.  What about Namco's Run for your Money game that had the single biggest increase week over week increase we've ever seen on the charts?  Leaving the top 50 and then bouncing back into the top 20 with like a 200%+ increase.  What about Medarot 7?  Little Battlers eXperience?  And also, you kind of invalidate your argument by moving the goalposts and exempting Capcom and SquareEnix - that definitely wouldn't have looked good for you...  :)

Also, if 3rd parties are in such a bad position on the 3DS, why is it getting all the AAA games?  Why was a new DQ remake announced and dated?  Why was SMT4 announced for the 3DS?  Why all this support then?  I'm not sure I follow...

These list do left some titles out, titles that don't have release date for example.

PSV http://www.gamefaqs.com/vita/releases

3DS http://www.gamefaqs.com/3ds/releases

As you can see, 3DS do have more titles coming in the next few months. However, if you only look at the titles releasing in December 3DS wins by a large margin. then again I'm not sure if these list are missing any titles. 

Now, if you are being one of those americans that think that all that matters is their country, then you may have a point. There are 4 releases for each handheld in North America. Including the Instant Game Collection Bundle, as one release. And when included the next 4 months there are 10 releases for 3DS and 8 for PSV. Not really a big difference

@pokoko you seem to ignore that there are quite a few "3DS haters" that do make you people look bad. I ain't defending 3DS supporters, just agreeing that there are quite a few posters that should really work on their arguments.

@mugen Well we are in a sales thread, even if this thread is located in the Gaming Discussion, sales are a factor that is bound to be included. You could even assume thats the point of the OP, more interested in the health of the systems rather than certain particular games. What you state is cool, you may have a problem tho, if sales do not pick up and reach a more healthier baseline, things will not be good.

Maybe I am crazy but I think Square Enix, sewing as how their Dragon Quest games have sold immensely on the 3DS, will shift their release of Final Fantasy X HD from Vita to 3DS :S

Well now YOU cherrypick Rune Factory 4 to defend your thesis after giving lame excuses for RE. Marvelous support 3DS so much that they shifted Senran Kagura to Vita even though it was doing so good. And 150k was quite achievable on Vita too btw.

And what are those games you mention? (Run for Money, Medarot!!????) Do people know about those? I'm telling you about established games/franchises, not some radom casual games that non-gamers buy on a whim. If 3rd parties succeed with such... let's say unexpected software I'm perfectly fine with this. But it's gonna be DS/Wii all over again, where playstation platforms eventually get most of the big titles.

Also, Capcom and SquareEnix aren't the subject here because if Nintendo hadn't struck some shady deal to get MH and DQ, 3DS would be behind Vita. Those games would sell on any system.

And by the way, only you care for that.

2 - Apparently they do know those, since it sold more than any Vita game. So, people know.

3 - Shady deal... lol. It's called business, you know, that thing that's good for both parts.

You're the funniest poster here, imo.

Oops! I must admit I overlooked that... My Marvelous argument fall into pieces. But shady deal I said, shady deal I maintain!

lol I guess 3DS bomba? :P
