"I doubt I would leave this company in 10 or even 20 years," said Toshihiro Nagoshi, as part of a new Gamasutra feature interview.
Best known for the Super Monkey Ball and Yakuza series, he's also heading up development of Sega Japan's foray into shooters, Binary Domain, which is due to ship on the PlayStation 3 and Xbox 360 Valentine's Day 2012.
While a lot of notable Japanese creators -- Ninja Gaiden's Tomonobu Itagaki, Mega Man creator Keiji Inafune, and if recent rumors are true, Ico's Fumito Ueda -- have struck out on their own recently, Nagoshi says he's staying put.
"It's not that I'm satisfied at Sega so much as I really owe one to Sega -- they taught me how much fun making games can be," Nagoshi told Gamasutra. "Unless something really drastic happens, I'm not going to leave on my own volition."
When it comes to other developers jumping ship from the big publishers, he said, "It's hard to say whether the trend is a good thing and for everyone's best interests, but a creator needs to be someplace where he can shine the brightest, and that's not necessarily always going to happen by going it alone."
The full interview, in which Naogshi describes how he's "fighting for his pride" to create a shooter that can compete with Western games with Binary Domain, is live now on Gamasutra.
