A game's concept is one of its most important assets. I feel that we must aim to satisfy both beginners and experts, and that hasn't changed since I was making 'Kirby' games.
I used to work at HAL, where I made 'Kirby' and 'Smash Bros.' After that, I became an independent designer, but I didn't have my own team.
In the past, I worked for HAL, and when working there, I had limitations and had restrictions on what I could create. They wanted me to make the next 'Smash Bros.' and the next 'Kirby,' and that wasn't the place for me.
I went out of my way to play games I didn't like or find interesting. Those ended up being a lot more informative for me. At home, I have literally thousands of games, and I think of them as pearls of wisdom from my predecessors.
