A deeper look into the Big 3's internal and partnered studios

[Kresnik]

Your Sony list is hella out of date.  Just some of the stuff I noticed:

 

• Project Siren missing from Japanese Studios.  If Team Ico count, then Project Siren count too :P.
• Incognito & Zipper Interactive have shut down from NA Studios.  
• Sucker Punch Productions are a first-party NA Studio.
• Studio Liverpool & BigBig have shut down from European Studios.
• XDev are a first-party European Studio.
• Sony also own a Studio in Foster City.  They assist third party devs with first-party titles.
• Game Republic (Japanese third party) have shut down.  I'm not sure I'd count Media.Vision as third party anymore (they haven't made a Wild ARMs game since 2007).
• Sucker Punch need moving from the third party list to first party.  Eat Sleep Play aren't working with Sony any longer
• Sanzaru Games (Sly: Thieves in Time); Superbot (PSABR); Bluepoint (all the first-party HD Collections); Mass Media (The Midway); United Front Games (LBP Karting; Modnation) would be worth adding to third party devs for NA.
• Quantic Dream (Heavy Rain); Tarsier (LittleBigPlanet); Novarama (Invizimals); Supermassive Games (Until Dawn); Housemarque (Super Stardust) would be worth adding to third party devs for Europe.

Might be worth updating the list of games they have produced/are working on too, but that's a job for someone else!
