Which of these PS3/Ps2 games should I get? I have a Month of free time coming up before UFC Undisputed 2010!

I preordered Ufc Undisputed 2010(I still play 2009 almost every day and 2010 seems like it's going to add so much), but it doesn't come out for another month and this semester ends in 5 days. I'm currently still playing through Valkyria Chronicles, Oblivion, Borderlands, Persona 4, and FFX sporadically, but I want a new game, hopefully for cheap. Here's what I'm looking at... 
  Eternal Sonata

I'm such a n00b! Let's just say that "G"= don't get anything/something else. I loved the Eternal Sonata demo, and I play the Fight Night demo all the time. I'm already playing through a bunch of games now but i'll have a TON of free time this summer and I want something fresh because I'm kind of stuck in a few games atm (Persona 4 mostly).

There is a Dragon Warrior XIII?  I did not know that.
