Indeed, it was one of the arguments that made me bought my 3DS XL first (a nice collector's edition Pikachu, one remains in the theme!)
And I have not been clearly disappointed!
The new graphic style is simply excellent, it gives new life to the license, and to rediscover many Pokemon (not all ...) the past, discover the 3D battles and mega-developments (some pokemon is transforming during the fighting in even bigger monsters, especially with the 3D enabled).
The music, always true to itself, remain the same despite a few new tracks or topical delivery of the former are clearly appreciable!
The little wink of the world map and the territory, thought and designed like that of France is a very nice little reference that will please all the French players!
The system and mechanical mainly remain the same, however it was a novelty: Hordes pokemon or we witness fights monsters 5 enemies against only 1 for us. Although not very useful or justified, it captures some pokemon more easily / quickly (due to their level is lowered because there are many more to balance with our pokemon, which itself is only.)
Really no downside to this game is if they are all Pokemon from the beginning present (and again? Is this really really cares when you know that there are already 450 to catch ...)
You still have not X or Y his colleague? But what do you expect? You can go for it head down, be sure that once again Game Freak will not disappoint you!
