I always try and come up with a clear theme when I'm making a videogame.
Nintendo's philosophy is never to go the easy path; it's always to challenge ourselves and try to do something new.
I think when you talk about competing against others, the problem is that you refer to something that's been done already and try to beat it.
I think that the entertainment industry itself has a history of chasing success. Any time a hit product comes out, all the other companies start chasing after that success and trying to recreate it by putting out similar products.
