Graphics 5
This game does not have VERY good graphics, but it's better than staring at the back of a boy in a red tunic. One of the reasons why it does not have very good graphics, is because in the side-scrolling view, take a good look at the hand Link is holding his sword in. It looks like an extent to his hand. At least the shield actually looks like a shield.
Sound 9
The game's sound when you kill an enemy reminds me of a classic game over. Just not as depressing. The music on the world map is a little tweaked up from ZELDA, and the music in the side-scrolling view is OH-SO good. Especially in dungeons. It gives me the feeling I am in a giant labyrinth in Link's prospective, only looking at his side, instead of through his eyes.
Addictiveness 10
I find this game so addictive because of it's Level-Up system. There are 24 Levels total, 8 for each category: Attack(Sword), Life(Heart), and Magic(Magic Jar). Also because there are spells to learn, which involve you going into side quests to receive an item, and coming back(Example: Leaving: Please help me find my father's trophy! Coming back with trophy: Oh, you found it! Please come inside! Then, you go to the back of the house, and an old man gives you the Fire spell.) These both make the game easier, because with the Shield spell, you can half damage received, and investing in the Life ability, will also allow you to do this, thus, making your overall defense 95% more than normal. There are also a lot of secret lives, and it just makes me want to find everything in the game.
Depth 7
The game is only 6 dungeons long, so I don't have much to say about THAT, but there is also 24 Levels, and for Level 24, you need like 2600 EXP, and you're fighting enemies that only give you 10 EXP most of the time(Occasionally, the EXP reaches above 100, but not so much.), and that adds another 2 hours to your game play, along with the fact that there are 5 spells, and you need to find the place the quest item is in, and there are also 8 Containers, 4 for Life, and 4 for Magic. 
Story 10 
Before Zelda 1, Ganon was(Obviously) after the Triforce, the powerful triangle of the gods. Zelda wouldn't give him her Triforce, and Ganon captured Zelda. After Ganon got his hands on the Triforce of Power, Ganon wanted to know where the final Triforce was, but Zelda wouldn't tell Ganon. And then, Zelda split her Triforce( The Triforce of Wisdom) into 8 pieces, and hid them in the dungeons around Hyrule. In Zelda 1, Link found the 8 pieces of the Triforce of Wisdom, and with the power of his Triforce, the final Triforce, defeated Ganon. And in Zelda II, Ganon's minions are trying to kill Link, and sprinkle Link's blood on Ganon's body to revive him. Not exactly a story for children, but it IS a pretty good one! 
Difficulty 10 
This is a very hard game, but still, I like that, and also it is what is expected of a Nintendo game, much less a Zelda game. Whenever you die, you restart in Zelda's Temple, with a total of 000 EXP/[50]. Also, you have lives until this happens, thankfully, but still you do die pretty often, especially on bosses, and also, on side-scrolling scenes with lava or water, and enemies, you will either run out of life, or fall into the lava or water A LOT. 
Overall 10 
I am proud to say, that this game is one game I will never, ever move on from. It's addictive, fun, hard, and is one of the best NES games ever.   

Pretty good review.
Your review was well written with good punctuation and grammar, and gave just enough detail in each category that made it easy and enjoyable to read while offering plenty of information on the game!
keep it up. 

Nice review. Zelda 2 has always been the black sheep of the series. However, as a standalone title, it's not half bad. It just doesn't live up to the rest of the series.

Chronobocca : Good review for a beginner, Zelda 2 wasn't that much as the rest of the Zelda games, but the game is still pretty good though, and this review is really nice, although it's short (typical for beginners to make), but on how much this review has, for your scale, this really descride the game really well and how it turned out, you have played the game, well, keep up with more review, love to see more from you.

i always hated this game for the random encounter battle scenes, the sidescrolling, and the incredible difficulty. among my personally unbeatable games

Nice review man, it is very good considering you are new, this is really descriptive and detailed and you broke it down nicely. Most newbies don't write this much in depth on the game, so good job. I would recommend though, spacing it out a little more would make it look more organized and neat, its not required, but I just think it would make it easy to read. 

Overall, i think you did a great job, if this is your first review then I think you are on to a fantastic start. All I can really say is, if you want to improve your reviewing, then you just have to practice, practice and practice. That is how you will master reviewing. So keep up the good work man and I'd greatly enjoy it if you keep making more reviews like this! 

This seems to be the unloved child of the franchise to me. I really don't see anything wrong with it besides the fact of being the most different from the rest of the series. It was all about Action Adventure, then the RPG element was thrown in, and everyone lost their minds. Glad to see you enjoy it for how it is. It's a fun game. Good job on the review.
