I probably won't buy X or Y right away. The jump into the realm of 3D isn't really enough for me to overlook the lack of addition or progression of features and gameplay, which is what I'm expecting at the moment.
I like my water/electric combo (Pikachu/Totodile in PMD: EoS) so I went with Pikachu/Oshawott in the newest PMD. Though right now I'm having to play as Oshawott because ~spoilers~ and eh. Also some parts of the story made me wish there was more fire types or that I chose Tepig.
But Companion Mode is the best thing ever. /plays as Keldeo froever.
