I played Xenogears the whole way through. I hated it. You thought Chrono Cross made no sense, this brings complicated stories to a whole new level.
Mainly, the game was TOO LONG. I mean WAY too long. There were points after being int he game for what seemed like 100 hours I was thinking "This HAS to be the last boss of the first disc". Turned out I was about 1/6t of the way through the game.
The second disc, then, turns into crap. They were apparently short on production time, so instead of putting in gameplay, TOLD you what hapenned. Like picture everything in Chrono Trigger from entering the Ocean Palace until you go to fight Lavos being TOLD to you, instead of playing through it. Just like that.
