Mario most definitely does not need to be kiddy. In fact, I would argue that the old 2D Mario games, as you stated, were completely not. These games were presented in such a way that left a lot of the storytelling up to the interpretation of the user (something Nintendo still does) AS WELL AS leaving the interpretation of much of the themes, character development, and other areas into the hands of the players. This really goes for the rest of old Nintendo as well. Everything was presented in a manner that all ages could enjoy without feeling the childish tones.
I kind of felt they did that well with Majora's Mask. That game had such immense depth and so many ways to see the game depending on how deep you wanted to dive into it. I also feel like Super Mario 64 did this beautifully as well. My hardcore BAMF uncle who loved to drink, smoke, and surf loved playing SM64, and I as a 7 year old also loved playing it. It was fun and accessible in a manner that didn't push and force strong elements that felt age or demographic restrictive.
(Yes, most of this was copy/pasted from my wall post).
I agree.100%.That´s a great post.
Anyway...old Nintendo >>> today´s Nintendo...imo.
