I liekd it, it's not like a typical RPG as to fully understand everything you have to play all 6 games, but currently only 2 are out (Xenogears/Episode 5, and Xenosaga/Episode 1)

But other then that minor detail it's still a great game, it has well over 40 if not hours worth of play time especially if you play the minigames and such. I say it's very worth it. Especially for a measily 20 bucks.
