I don’t know how new you are to programming and modeling in general but ambershee has a point.
So Nintendo really gets on people who use their brands withou permission even if it is a not for profit project. It still gains you publicity and makes Nintendo and HAL look bad. What you could do is use this as a fan project to help you learn since you are new to UE4.
I do rip offs of games for ideas as learning projects all the time to help me learn the algorithms if how to do something. Like right now I’m trying to make a bomber an clone, a star fox clone, and a motor storm clone. When I get bored from my actual projects I hop in one of them and keep trying to learn how to make a mechanic work.
