Let's begin this review with the graphics. They are simply amazing for this period of time! If you've played this game, you know exactly what I mean. For the time this game was released, the graphics for this game were legendary!

The same with the graphics, the music and sound in this game were legendary for its time. In fact, I would say it is better than some of the soundtracks we hear on modern consoles. World 1-1's music will be stuck in my head forever! The sound effects are even better than some later games. I'm looking at you, Mario's Time Machine! No offense if you like that game! That pretty much covers music and sound, so let's move on to addictiveness.

Is this game addicting? Oh yes it is! It is one of the most addictive games I've ever played!. That says a lot, because I've played some pretty addictive games before,like the original Sonic games. Don't get me wrong, they are great games, just like this one, but this game comes to my mind first when I think of classics and addictiveness.

The story in this game is pure classic. Bowser kidnaps the princess and Mario has to save her. But he keeps showing up in the wrong castle. For the time, this was the best story ever! I'll even say it is way better than some other stories presented many years later. I'm looking at you, Sonic '06! 

This game is huge for the time! It takes a lot of practice to master this game. It was slightly easier for me, since I grew up on Super Mario Bros. Deluxe for the Game Boy Color. This game might be the biggest game on the system before Zelda! That's why I rated it so high.

Is this game difficult? Yes it is! It can get frustrating later on. I will give you a hint, though. Don't get frustrated. This game is supposed to be fun. Don't get mad just because you can't beat one level! That's how I beat Super Mario Bros. Deluxe, which is basically a remake of this game. So the same rules apply! 

Overall, this game is a great classic that will be remembered as one of the best games of all time. Just play this game, it's pretty much self-explanatory once you play it. I highly recommend this game to anyone who has extra time and would like to play the game that started it all.

Excellent review, especially for a user who's new here! Keep up the good work! Also, I grew up with Super Mario Bros. Deluxe for the GBC as well! I played that version a year before I played the original NES version.
