Based on Metal Gear series creator Hideo Kojima's comments about the two teams working on Metal Gear Solid: Rising and Metal Gear Solid: Peace Walker, we're guessing Kojima Productions is home to daily office brawls between the two.
Kojima tells Gamepro that the two teams have a sort of rivalry going on as each title is developed. Why? It's a simple snobs versus slobs situation, with one team—the Peace Walker fellas—getting the short end of the stick when it comes to money and hardware specs.
Obviously the PSP can't make the technical prowess of the PlayStation 3 and Xbox 360, but that apparently hasn't stopped some corporate bad blood between the two Metal Gear Solid teams. Kojima goes far enough to say the teams are "not good friends." Why do you say that Kojima?
"The reason why I say they are not good friends is because the PSP is working day and night to make it even better than MGS4, but of course they can't do it because of a lot of restrictions," he tells Gamepro. "On the other hand, the Rising team is using loads of money and loads of capacity and hardware specs."
So, while the Rising guys and gals are pissing away yen like its their job, lighting Cuban cigars with 10,000 yen notes while the Peace Walker team searches for crusts of bread in the Kojima Productions kitchenette to survive. Or at least that's how we're envisioning it. They're probably just not holding the door for the Rising guys on the way into the office sometimes. Or bowing at an angle one degree higher.
My version of this rivalry is better.
