While on a trip to California, GameFreak director Junicihi Masuda and game designer Takeshi Kawachimaru were interviewed by G4. Below are some excerpts from the interview.

G4: Pokemon Platinum's concept is based on some heady things like Einstein's theory of relativity, matter, and antimatter. Would you kindly expand on that for the G4 audience?

Takeshi Kawachimaru: I was the one that set the direction for Platinum. Mr. Masuda came to me and explained the original concept for the Pokemon Giratina. He mentioned anti-matter as something -- it's there, but it's something you can't see. Mr. Masuda gave me a lot of key concepts to design around -- matter, antimatter, Einstein's theory of relativity. I was the one that had to make those concepts a realization in a Pokemon game -- both visually and implementing certain tricks into the gameplay to give the player a sense of bipolarity.

There's a concept in particle, in physics called CP violation. It helps explain the relationship between matter and antimatter. The relationship is bipolar. The reality is that anti-matter is something that's very, very fragile. This concept weighs heavily in how we came up with Pokemon Platinum's Distortion World.

G4: Legendary Pokemon have been getting more powerful since gamers encountered Articuno, Moltres, and Zapdos in Kanto. Giratina, the cover Pokemon for Platinum, is ridiculously powerful. Arceus is like the god of all Pokemon. Will there be anything more powerful than Arceus in future games?

Junichi Masuda: In Diamond and Pearl you have Dialga and Palkia. In Platinum you have Giratina. There are three legendary Pokemon and there's a relationship between the three. From there we have a story to move onto with other legendary Pokemon, but at this point that's all I can share.
