Woah, i remember playing that game, and the villain was some big breasted middle aged lady and you played with a "cool" version of Yuna.
I was very young back then, like 6 or 7 years old, i never noticed how good the title theme was, it's much better than FFXIII's.
Man i really need to play FFX-2 again, i had no idea what was going on and i just kept going forward, the only thing i remember that Yuna and co. were singing some j pop with some giant frog in the very beginning of the game.
It's a good thing they are including it with FFX hd. --- Versus XIII is probably a PS4 game now. Formerly known as HeartKey_XIII
