Even though I have wanted this game, be aware of the changes of the base powers of moves that you like.
1: ALL moves related to Blizzard, with the exception of Gunk Shot and Focus Blast had their base powers decreased to 110, which is bad because they had framed the concept of the moves by simply decreasing the base power, just like Fire Blast and Hydro Pump. (Would you even imagine a time what if these moves had the same base power as Stone Edge and Earthquake?)
2: Aura Sphere, one of Lucario's moves had its base power decreased to 80 from 90, which is bad because another move had its power decreased.
3: Starting from this game, Overheat had its base power decreased to 130, the same base power as High Jump Kick. the same occured with Leaf Storm and Draco Meteor. This made me very angry.
4: ALL 3 versions of Flamethrower had their base powers decreased to 90, this made me angry to find out when I looked them up on Bulbapedia.
Some moves like Bubble had its base powers increased.
Also, there are other features that may be unnecessary for me as a player.
1: You can customize your trainer, but you can notice the unnecessary sunglasses for the trainer (Yes. Both the male and female), but you can choose different hats.
2: Pokemon-Amie is a complete joke. In my opinion, an avid player would think that he or she is wasting time in the feature. One time, I even saw a screenshot of a Yveltal in that feature! Since it is the only way to get Sylveon without trading, I would pick another Eeveelution such as Umbreon or otherwise Jolteon.
3: They had ruined the Dragon-type's cool physique by introducing the so-called "Fairy-type", which is immune to the Dragon type, resistant to the Bug type and strong against not only the Dragon type, but also the Dark and Fighting type. However, Fire-type Pokemon (like Typhlosion and Moltres) resist Fairy-type moves. Also, the two types Fairy-type Pokemon are weak to are Poison-type (like Seviper and Crobat) and Steel-type Pokemon (like Skarmory and Aggron).
4: The two games introduced the least number of Pokemon, with only 69 (Whoa, this is less than the amount of Pokemon that were introduced in Gold and Silver!). This also introduced the least number of moves, as well as abilities. Everything about these 2 games appear to be small. Game Freak appears to be "Slaking" off with the games.
However, there are positives to these 2 games.
1: Like Pokemon Battle Revolution, the moves can hit the Pokemon while more action is added to the battles like when a Pokemon gets hit or Faints. Take a Gengar battling an Ursaring for example. When that Ursaring faints, it drops to the ground while the area where the Ursaring was standing shrinks and disappears.
2: The moves are getting more sophisticated as more moves are introduced like Powder, a move that Vivillion can know and Boomburst, an attack with 140 base power and the move that Noivern knows. Aurorus can also know the move, Freeze-Dry, a move which is super-effective against Water-type Pokemon (like Clawitzer and Simipour). Also, Hawlucha's signature move, Flying Press can deal both Fighting and Flying-type damage to the opposing Pokemon!
3: Due to the positive reviews to this game, It looks cool, but note there are many changes going on with the game experience compared to Pokemon Black and White.
Overall, I would rate it 3 stars.
