And media molecule is first party. How do you know Naughty Dog didn't think of Uncharted and then decided to use Sony's money to make it? Of course they would have no other solution but even then logically its always the developer who makes an IP, not a publisher. Sony has never made an IP before, never will because they are the publishers, unlike Valve who are publishers and developers themselves.

Sony isn't represented by a single developing studio, hence they never made an IP. How can one call Killzone as made by Sony when its made by guerilla games? Guerilla games could have easily bought themselves out and made the IP, but they choose to do it with Sony instead. Sony does nothing when an IP is considered other than funding a project.

Besides infamous right now wouldn't be the infamous we have because of Naughty Dog helping Sucker Punch. Sucker punch and insomniac have helped naughty dog as well.

What is the best new Sony IP created this gen?

I actually preferred Killzone 1's campaign over Killzone 2. It was just the AI and shooting mechanics that were horribly flawed.

Uhm.. no, in my opinion these questions aren't the same

for my understanding the first ones conditions are, that Sony has to own the IP ("Sony IP" - an IP Sony owns) and that the IP must be created this gen (it's not specified by whom), while the second ones conditions are that the IP has to be created by Sony and this gen

Locco Roco and Patapon for me.  Since no one appreciates portable around here LBP followed very closely by Uncharted.  

 People are being way to pedantic here and derailing the thread nit picking over what is effectively the English language.

 The role of a publisher isn't just giving studio x a load of money and saying 'create something'. It's a relationship between publisher and developer to work together to create the product, the publisher has alot of input in the creation of the IP more on the business side of things - making it a marketable product that will sell, making decisions that will control the budget and developement schedule whereas say, Insomniac will focus more on the individual level creation.

 It's not true to say Sony created these IP's on their own but it's also not true to say they had a substantial role in the creation of these IP's and thus any debate is futile.

AND if we do want to start dissecting the English language - the thread title says best new Sony IP created - that is the best Sony IP - an IP that belongs to Sony (NOT an IP created by Sony) thus InFamous, Resistance and the rest are valid answers for that question and they are Sony IP's that have been created.

Were those created this gen?

Yes.  PSP and DS started this generation. Just like the 3DS and PSP2 will be the first consoles of this coming generation.  No one will see it that way or care as portables aren't nearly as deeply ingrained outside of Japan.  Hell the Wii is just a home based DS with worse third party software. The PS3 shares the same graphical user interface as the PSP as well boasting many multimedia features like it's portable brother.  

Well, don't think they're that under-appreciated, I played and loved them both.

Uncharted for me. Resistance gets quite a lot of undeserved flak and I think the third game is going to be very special. Infamous as an IP could give Uncharted a run for its money depedning on how Infamous 2 turns out. Demon's Souls is fantastic too; Uncharted is best with these 3 close behind.
