From the Super Mario Wiki
“I have never consciously separated casual users and hardcore gamers when I design a game. For the past 20 years, I have always been trying to make games so that anyone -- as many people as possible -- can enjoy them... I cannot help but say that I love my job of making games from the bottom of my heart.”
Takashi Tezuka (in Japanese: 手塚 卓志), sometimes credited under the name Ten Ten, is a veteran video game designer currently working for Nintendo.
