I've been playing since generation one, too! Which game did you wind up getting? For me, it would have to be Blue, which was given to me by my dad as a present for Christmas, along with plenty of other games. For me, it was quite addictive; regardless of how tough I tried to put it down, I simply couldn't. To finish, it had only taken me about six days or so, if I remember right.
Ah, same here. To finish X and Y, it took me only about a week. Like above, this one was pretty addictive, too, especially due to its all-new graphics and features. As far as latter goes, one of my personal favorites has to be character-customization. I've always been wanting to personalize my player, and being able to finally do such a thing was dream come true. How about you--what is your favorite feature?
