Also, Super Mario Bros 1 is probably my least favorite Mario game. Too hard, controls are clunky and the level design is really poor.
What? SMB1 is literally the template for all platforming level design and teaching tropes through gameplay.

I try to go through the game at least once a year these past years, but it's just not the same on any of the emulated platvorms. It's way easier with a good old CRT and NES.
