Pokemon Rumble Blast was an interesting twist on the Pokemon genre. You see, in this game, Pokemon are toys. They compete, similarly to the other games, to become a Pokemon Champion. Unlike other games, however, the Pokemon have no trainers and are independent thinkers. They can talk, form alliances, and have rivals. I'm not gonna delve more into the Story until we get there though...
Graphics: 5/10
For this day and age the characters just look too blocky and undefined. If Minecraft were Pokemon and the blocks could be more than cube shaped, it'd be this game. However, the Pokemon do look kind of "cute", per say, and the Pokemon are pretty much done to scale. (For example, a first stage pokemon is the smallest, a second stage is bigger, a third stage Pokemon is even bigger, and a legendary is biggest.) Other than that, there is honestly not much to say about the graphics. For our day and age, they aren't great. Don't worry, this review gets better from here.
Sound: 8/10
Wow. That main menu music was amazing. Loud, fast and really has the feel of something epic. It set the stage for the rest of the game. The Battle Arena was also fast-paced and had a frantic feeling, which really added to when you were in a tough situation, on the brink of losing. All of the forests and beaches had light, carefree music, while all the towers, caves, and fiery areas had slow, mysterious, almost spooky music. It was spot on. Where the sound slightly fails, however, is when attacking. Sure, the vines from several attacks would make a cool slithering sound as they moved in on the enemy, but the general variation of sound effects seemed kind of lame. So, 8 of 10 seems like a pretty good score.
Addictiveness: 6/10
There are several things that add replay value to this game. One, you want to collect all the toy Pokemon from all the areas to complete your Champion team and complete your bestiary like collection for each area. The first time you complete the game, chances are you won't have completed your collection fully and wholly. Also, when you beat the game, you can still improve your team by finding more, stronger Pokemon and using Move Vendors. In conclusion, you can't do to much without resetting the game, but you completionists out there can surely have a field day with this one.
Story: 9/10
This story starts quite innocently, but quickly becomes an epic struggle between good and evil. You're knocked out and wake up just outside Toy Town. You enter and find that the residents are kind; for they let you use the Glowdrop Fountain. Glowdrops heal Pokemon like a Pokemon Center does in the traditional games. You start a rivalry with another group of Pokemon, when oh no--- someone starts stealing the Glowdrops from the town's fountain. Your rival is the most likely culprit, until you start progressing through the game. You find out other town's have been losing Glowdrops, too! Who IS the real culprit? Find out as you become champion!
Depth: 7/10
It has a slightly long storyline to play through, so that takes some time. As previously stated, completionists will have a bit more to do with creating the ultimate team with Move Vendors, and completing the "Pokedex" for every area. I figure that that could actually take a few months for an average person, so the depth is 7 of 10.
Difficulty: 3/10
Ahhh... The bane of this game. The difficulty is non-existent at points, and barely in the game at others. There is no strategy, just wailing on your foes with your best move, mashing buttons as rapidly as possible, or sitting back as opponents wail on each other in Battle Royal. The most difficult point in the game is re-adjusting and making more team members in order to take on a "harder" Battle Royal. I was feeling generous when I gave the Difficulty a 3. Honestly. It's non-existent.
Overall: 6.3/10
This is my first game review; open to constructive criticism.?

MysteriousPanzer : criticism no i think you actually did very well because most of the user's first game review are 5 words long but you put lot's of detail into all catergories and you did very well good job

deg2000 : Thank you! I was already planning on making more reviews, but your positive comment has really encouraged me to make better quality reviews.

MysteriousPanzer : This definitely wasn't a bad review all things considered since it was your first review, the only thing I might say you should try doing is spacing out each section like: Graphics: (words) and then leave spaces in between, just so that way it would be easier for some users to read. You did a great job though!

Other than the spacing, this is a pretty good review, if this is a first review, then you really came off to an awesome start, you have almost 700 words, you are detailed in each section of the review and you are organized with your review, which will be even better once the spacing is fixed. So altogether, you are off to a fantastic start and your review really went into a great amount of depth with the game, you should give yourself a pat on the back for making a review like this on your first try, because like deg2000 said, most new users make like 30 word reviews on their first attempt, so nice job man. 

Overall keep up the good work and keep reviewing so that your skills will only increase. I think you have great potential to write great, and even possibly featured reviews in the future.
