While the first New Super Mario Bros.
game was initially a success on all counts, in hindsight it seems rather mediocre.
The main problem is that it's just not very memorable. I can't remember very much about the game save for the Mega Mushroom, Blue Shell, the final castle, and some of the music. Sure, that may not sound like much, but games like Super Mario Bros. 3
and Super Mario World
were very memorable, with a great many levels that really stick out a decade or two later.
The other problem is that it's rather easy. Miyamoto openly regretted doing this, and I can't say he's wrong.
Though my review may seem rather short, it's just that there's not a whole lot to
the game, and that's why I don't like it. In short, it gets a 2.5/5
