You know, I honestly don't remember. I tend to take my time and try to enjoy the game and not gobble it up without chewing. The last one I "finished" was Moon on the emulator at least six months ago, which took a long time of sporadic playing, and I haven't gotten around to the postgame yet (been generally busy).
I never really think of finishing a Pokémon game. For me, it's just that you're past the story and at your leisure to go about doing whatever you want, whenever and however you get inspired. In Black I liked breeding Egg moves for a time.
