Apparently the Metal Gear Solid: Peace Walker and Metal Gear Solid: Rising teams hate each other. Okay, that's a bit of an exaggeration, but even Hideo Kojima has admitted that there's jealousy and tension between the two teams. In an interview with GamePro's Travis "Pretty Boy" Moses, Kojima said:
"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. On the other hand, the Rising team is using loads of money and loads of capacity and hardware specs. If you could imagine the PSP team looking at the Rising team saying, they have all the money and specs. That's the one reason why they are not good friends."
What's amusing is how Kojima views the situation:
"It's interesting for me to see the team members act in this way. This was never before because it was always just one small team. Now we are much bigger. So it's really interesting for me to watch the team right now."
That's great that it's interesting for you Hideo. Let's see how interesting you think it is when Kojima Productions employees start throwing each other out of windows! Seriously though, the competition might be a good thing; I've met a lot of people that work better when they have a chip on their shoulder. I'm not sure if that feeling is prevalent in Japanese workplaces, but it could be a motivator. Then again, I've met a lot of people that generate crappy results when they're bitter. I'm curious to see how it all pans out.
Also, in my head I see Kojima watching his employees like a kid watches an ant farm...but perhaps that's just me.
