[Kenryoku_Maxis]

Mario has always been grown up. He's been in his mid 30s ever since his conception.

Also, this art style of making Mario look 'real' or 'Gritty' isn't new. Its been around since the late 90s in Japan.  Thyey have similar designs for everything from Cor. Sanders to Marvel Superheroes.
