What about them?
Both IU and EM are on the lower end of the Library. IMO, the X360 catalog goes like this (in terms of how good it is):
Tales of Vesperia
Lost Odyssey
Blue Dragon
The Last Remnant
Eternal Sonata
Infinite Undiscovery
Enchanted Arms
Phantasy Star Universe
Kingdom Under Fire: CoD
Haven't played O:D, SF3 or Zoids:A yet.
Back from the dead, I'm afraid.
