It was a decent RPG. It's not my favorite but I liked it. There were a few complaints I had though. They only had one battle theme for both regular and boss battles which stunk and the music was lacking in the dungeons but what it did have during the cutscenes and all was excellent. After all, the composer was Mitsuda, the same guy who did Chrono Trigger,Chrono Cross, and Xenogears, so how can it not be excellent.
The battle system could've been somewhat better. It sometimes felt like I was just using Special Techs a lot. Some of those Techs, while cool looking and all, got a little old after you saw them for the hundredth time.
I enjoyed the characters and story. Albedo is one of those strange and creepy villians.
The religious symbolism was . . .interesting to say the least. I doubt it's quite as strange as Evangelion which I haven't seen so I wouldn't know everthing about what it's religious symbolism contains. I didn't notice anything anti-Christian and I doubt the maker's intended for it to be taken that way. I think it would be actually less offensive then Xenogears might be.
Oh yeah, another thing I enjoyed was the in-game database. The game's script was well written and has little references to everything from H.G.Wells to The Wizard of Oz. The database was helpful for when you overlooked something and the entries were an interesting read.
