I’m not saying those are the only groups that enjoy their games, just who Nintendo aims to sell to primarily, and what they do with marketing more than what they do in the games themselves.

While they do make games that are generally simple to understand, pick up and enjoy by all, they really show this in their ads for the games and the systems they make. They focus on accessibility, family time, etc. Not necessarily graphics, computing power, or anything of a technical nature.
