The Graces cast had to grow on me too, except for Pascal. I loved Pascal from her first scene. At first Huburt was my least favorite favorite, but grew to be second behind Pascal. I think it was his, "We should always give it our best. That wasn't it." Victory quote, so very deadpan. And his interactions with Pascal was the best. And I liked Sophie's hair. There's a couple of funny victory quotes revolving around them. Putting Pascal in her bathing suit ruins any serious moment. Especially since you can only get it like right before the final dungeon so it's pretty much serious at that point.

Abyss is my favorite though. Again because the cast. Especially Jade. Jade is the best character in the entire series. And Natalia is my go to character to play as. I've only other played Phantasia, Eternia, Symphonia, Legendia, and Hearts.

I have Xillia downloaded, I got a bundle with Graces, but I haven't played it yet.
