Pokémon X is the best Pokémon game ever.
I brings a tear to my eye just to think about how long I've been waiting to play a game like this. 3D environment, villains with seriously dark motives (genocide), and a plethora of new types, if you're a die hard Pokémon fan, buy it. If you're interested in the series and want a good place to start, buy it.
Overall: A.J. Bauer commands you to buy it
