Sanzaru Games Inc. is the company making the fourth installment of the Sly Cooper series, Sly Cooper Thieves in Time. Sanzaru decided to make Sly 4 because the Sly Cooper series was one of their favorite video game franchises, and they were sad too see that the sequal of the series wasn't being made. here's what Sanzaru has to say about their company:

Who are we?
Sanzaru Games is an independent console video game development studio founded
in 2007 by seven very experienced game developers; our mission is to bring
together a group of talented individuals to share a common vision to develop fun
to play, visually stunning and technically spectacular console games. Over the
last 4 years the team has grown to over 60 and will continue to expand as more
talented and experienced developers are drawn to the studio.

What’s in a name?
Sanzaru are the famous 3 wise monkeys – the founding philosophy for Sanzaru
Games is that great games are a function of good design, beautiful, clear
visuals and a strong technology base to deliver these. Should any one of these
three pillars be missing then the game will suffer.

What are we working on?
Sanzaru Games is a registered Nintendo, Microsoft and Sony console developer.
We just finished up working on the first Mystery Case Files™ game for the Wii,
The Malgrave Incident™ and will have more cool things to talk about at E3 this
year!

Where do we file our taxes?
Sanzaru Games Inc. is a California corporation.
