If you consider the last one as New Super Mario Bros U, then sure, we are over a decade. However, Mario Maker, and especially Mario Maker 2, are so wonderful and repayable, that I feel no need for a new 2D Mario game. I get that a game like Wonder is going to have “curated” levels, and things can work more cleanly, but the volume of quality levels in the Mario Maker series is enormous. Anyway, I just find it odd to see your comment, which seems to ignore these titles.
