Overall: 9.9
Overall, the Pokémon Ultra Violet Hack is a lot like Pokémon Fire Red.  The only difference is that all Pokémon are obtainable in the game, and you can catch your first Pokémon.
Graphics: 9
The graphics are similar to Pokémon fire red and other GBA games so I rated this a 9.  I would've liked to see some new graphics but I'm happy with how it is.
Sound: 10
This is just my personal opinion but I LOVE the old beeping music and sound.  Although not much was changed in sound, I'm glad as I don't like the newer sound effects.
Addictiveness: 9
With all Pokémon being catch able, the addictiveness scales as you just want to catch 'em all.
Story: 5
Again, the story is almost EXACTLY the same as fire red, so I rated 5 as the story wasn't original.
Depth: 9
Depth. I rated this one 9 because now you can actually take time and catch all the Pokémon!  That alone adds a lot of depth to this.  There are some new areas to explore, but not too many, but still, this adds more to the game's environment.
Difficulty: 7
The Difficulty on this one was what you expect out of a Pokémon game.  Almost everything is determined by luck, enemies make stupid mistakes, and you get stronger way faster then the opponents do.

Well to start things off I could say you can add more details to this review in order for this to be a well put detailed review, a little organized yet you can make it a little more neater. I can say I agree with review 100% though! I'm not done yet though. You could put a little of your adventure of the game into the review. It was not to short yet a little more words to make it a 300 word would be swell. So from this I see no other mistakes or holes in this review. Anyway you did good so I say you should keep up the work and make more reviews!
