Xillia 1 (haven't played 2) isn't underrated. I think the fact the Vesperia was amazing and did so much more, that Xillia and Graces don't seem to be measure.

To me Xillia was picking up, and than it ended. It just felt short, I don't usually say that about JRPGs.

Hopefully, microsoft can't ignore it then.

Play Xillia 2. Its a lot better than the first.

Every time Microsoft touches a Japanese developer they get sucked

Hmm maybe later, but really everyone should play Vesperia, a part of me wishes it did release for the ps3 now. It was cool at first to be part of an exclusive group, but now I kind of want the ps3 crowd to be able to play it. 

You do get back to Fenmount and Its good you picked Jude as main character. Milla's story gets confusing at one point because she leaves the party for a long time and a lot of things happen without you knowing.

They're just way too childish for anyone outside of japan.

And what isn't childish ? Final Fantasy?

Tales of Xillia 2 isn't underrated.  The main character is a mute with no personality, he just goes with the flow and the side quests are handled awfully and are so boring and repetative, which wouldn't be that big of a deal except the game forces you to do them before you can proceed with the main story.  Couldn't force myself to finish it.

Final Fantasy isn't childish no, especially when compared to the Tales series.
