Square Enix Games (The Listal Collection)

The hit of Kindgom Hearts series~!

The hit of the game markets in 1997. Used to be rated as the best game of the Final Fantasy series ever, until, of course, XIII comes out.

That was also a great game, but it's succeeder X-2 Just sucked! The graphics in the two games differ a lot... and new characters were added in X-2, but, X is better with that it's graphics, gameplay, and story.
It was impressive.
Some of the characters of X also appear in Kingdom Hearts. Tidus, Wakka, Selphie, Yuna, Paine, Rikki... wait up, Yuna and Paine etc... are from X-2, aren't they?
I'm confused!
