X-2 is such a fascinating and awesome experience when immediately played after X. If you can see past the J-Pop exterior, it's amazing to see how the world has grown, changed and expanded following the events of X; it's amazing to see how Yuna herself has changed and grown (again, flashy exterior aside); and gameplay-wise, it's night and day compared to X - hyper non-linearity vs. hyper linearity, and the best and fastest ATB yet compared to the predictable/boring-as-mud CTB.
It's such a bizarre, perfect complement to the X experience.
I'm so over X's battle system again. It's so rock-paper-scissors, especially early on, and while the UI/responsiveness is fast and snappy, it's quite frankly boring. CTB is a snore compared to ATB. Total backward step.
