This will be a toughie for me because it has been a long time since i played Pokémon ranger 2. Well, if memory serves, I might get everything right. 
Graphics: 9. When i was younger, i hated 8-bit games so i liked DS games because They had more epicness and Pokémon is better than Mario because i didn't know Mario except he wore my favorite color and he rode in a kart.'  yep. That's what i thought about Mario and my favorite series mega man. Truth to be told, i never heard of mega man when i was 8 or 9 years old. But anyways. I liked the graphics when i was younger. When i saw darkrai i was like "whoa" and i was a scared...just for i second then i was like "DARKRAI! I WILL GET YOU!" 
Sound: 9. I dont remember the music. Except for the capturing song and the song when you ride empoleon. I heard a remix of Darkrais theme buts that's it.
Addictiveness:10. Oh i loved this game that i played this game non stop. I loved this game so much that i finished it in a week. Each time i got sick and came home from school, i played this game every day. 
Story: 8. So your a Pokémon Ranger in training in the game and you can chose your Gender and your name. Your in school with a boy and a girl. One day a Pokémon ranger visited the ranger school.  that's all i remember about the story. I'm no fun.
Depth: 3. This game was a piece of cake for me. Sings how i have finished a lot of Pokémon RPGS (RPG mean Role playing games.) this game wont be to difficicult and its very fun.
Difficulty: 5. RPG Masters can beat this game in a day if they want but its not fun just to ruin the surprises. The game was very fun and not to challenging.
Overall: 10. This game brings back childhood memories and is very fun and excising. I hope i can play this game soon. But for now i can look for the music and listen to it.

Okay so first off this review was nothing excellent.
 
 What I would advise you to do is to play the game again to refresh your memory because it seemed you forgot some very important things here in this review.
 
 The graphics it seemed like you got sidetracked on.
 
 The story I was still thriving for more info on.
 
 Finally the review is a little hard to read all scrunched up together like that.
