As far as originality goes, Xenosaga is very good. Nowadays, not much can be original with so many ideas being used and overdone. But, Xenosaga uses this idea of combining theology, science fiction, and fantasy. This is not done often, or not done at all! But in terms of game play, the aspects were all seen at some point, but twicked to fit the story perfectly. The game is pretty serious from beginning to end, but there are moments of lighthearted humor to lighten the mood a bit. While playing, it always tends to be a long cut scene and then a long dungeon rather than a mix. This will be good for story-driven people and people who likes movies, since the cut scenes are pretty much 30 minutes to an hour long anime episodes.
