Nintendo has defended itself against the claims that the Mario franchise and the recently released New Super Mario Bros. 2 for 3DS is suffering from sequelitis.
Speaking to Kotaku, Nintendo president Satoru Iwata said "We only create a New Super Mario Bros. title one per platform."
He went on to add: "I think we'll probably go ahead and continue at that pace. That being said, that's probably Miyamoto's choice, so I can't give you a 100% guarantee that that's the pace we'll continue at."
"They do share a name and there are some components that are similar," "That being said, these are two very unique and separate titles... We have a Mario you can play in the palm of your hand and a Mario you can play seated in front of your TV. I believe the two titles are unique enough that I wouldn't say that I'm super-worried that people are going to be confused."
