What is there to say that has not already been said about this classic? Oh yeah. Nothing. This game basically DEFINED platforming games, CREATED a legacy of games still being continued today, and made Nintendo a front-runner in the battle for the best video game company.
Graphics : 10.
Now this is just comparing it to games of the era, but these graphics were REVOLUTIONARY!!! I mean sure, compared to the X1, they look like trash, but for the NES? Great. Just...Great.
Sound : 10
I don't know any gamers who I can't just walk up to and say, "Hey! Sing me the Mario song!" and they wont go, do do do do do DO, do.
Addictiveness : 10
If it wasn't addicting, would it be THIS famous? No.
Story : 3.
Bowser gets peach, Mario gets her back. Nothing much here.
Depth : 10.
There are 8 worlds, with 4 levels in each, one of which is a castle. 8 castles, and 24 other levels. Yeah, its big.
Difficulty : 5
This game is pretty easy....until world 8. Then its DEADLY.
Overall : 10.
Super Mario Bros is one of the greatest retro games, OF ALL TIME.

I like that you talked about each category and put your ratings for each category! That's the perfect way to review a game on vizzed.

Other than not going into much detail on each category, your review is great! Review some more games in the future

Like Pacman said, you did a good job with adding different categories to your review. The only thing I'd suggest in the future is adding more detail to each category. Other than that though, you did a decent job.

As my peers said, you had good structure but lacked details. One thing that always helps is comparing the game you review with others from the same genre/ era. How do the graphics compare to other NES games?
