Well, I returned my copy of Mario Maker today. The selection of levels is just not improving (I'm partially to blame, I make hard levels too), and the palette of items has exhausted it's cleverness. I'm also tired of people skipping my levels and I'm tired of having to sift through self-playing and ball-busting my hard levels.
After playing a popular maker's levels, I noticed either praise for. "Being like a Mario level" or just because it was easy and I realized why this game isn't satisfying to me- everyone wants to bust people's balls bu not have to deal with it themselves, and if they scale back the difficulty it just feels boring since there is not linear structure to playing the levels. Nintendo certainly didn't do a good job of trying to filter the levels themselves.
Maybe I'll pick Mario Maker back up again in the future, when the creators have matured a bit and the level design has, as well. But until then, I have more important things to work on, and I also realized that I need a long break from all Mario because it's dissatisfying to me.
