Eternal Sonata was nothing more than the leftovers of Tales of Vesperia. They use the same engine by similar teams. However, all of the resources to make a great game went to ToV instead of ES. ToV is superior in every fathomable way, and then some (my JRPG of the gen for consoles).
If you can, snag a copy of ToV and see what ES was supposed to be. FWIW, I own both, and bought both on launch day. ES was great when it came out, as its cell-shaded graphics were godly back in the day. However, ToV is better in every way, with a similar graphical flair. Better story, combat, characters, gameplay, the whole 9 yards. Heck, the same voice actors are in both games. Try to guess which ones are which after playing ES, then moving to ToV.
Back from the dead, I'm afraid.
