#20 Super Mario Maker 2
Given my profile pic I guess it is not much of a surprise finding a Super Mario Maker game in my top games list. I have a bit of a modding vein in me having built small mods for a few 2D Zelda games as well as Fire Emblem. Super Mario Maker made it possible with official software to create my own Mario levels, sign me up! The first game was in my opinion for long the only reason to own a WiiU, when the second game dropped on Switch, I dropped my WiiU.
If I only got to play Mario Maker, I think that game single handily would scratch my Mario itch. The first game had better controls with the gamepad but the second game had more features and is still the better game. Now, if only people was better at game design so that I could play and enjoy more Mario levels than about 1 in 10 being good and 1 in 100 being great.
