I mentioned this in the community thread, but some of the j-pop stuff in X-2 is annoying me a little more now then it did when I was younger. I would think I would be "over it" and feel the opposite. I cringe when Yuna says something faux-tough and then the girls hop and high five each other.
I know the game is so much more than that, though.
It's pretty front-loaded with that stuff -- the opening mission in particular. Later in the game it's definitely still there, but not quite as in your face all the time.
