Same for me, I'm going all Kalos Pokemon on my first playthrough.
I'm gonna try to stick with Kalos only, but if I can catch certain other Pokemon, then I will. At the very least, I'm sticking with Chespin the whole way through. --- Official Chespin of GameFAQs! :3 No, I am not going to run, I am not going to hide, I am going to take a stand and fight!
