Since it's already the 13th, here's the next right away.
#49: Super Mario Bros. 3
It's a fantastic platformer with some amazing level design.
I played it for the first time on the Switch with NSO. It's easily the best NES game and the one that aged the best.
I have zero nostalgia for this game, since I played it for the first time in 2019 and never since. Usually either this game or Super Mario World are named as the best 2D Mario platformer. I think this one's better.
It's level design is top notch with some great variety and challenge.
It looks great to this day.
Absolute must play if you have NSO.
