Eternal Sonata. It's a J-RPG that takes place inside Frederic Chopin's mind while he is on his death bed. Good cell shading graphics, thought provoking story, and the attacks change if you are in the light or in a shadow. Really flew under the radar when it came out a few years ago.
Isn't this the PS4 section of the forums? Why are people responding with answers that aren't PS4 games?
I haven't run into a great JRPG on the system yet, but I just ordered Ni No Kuni in hopes I can change that.
I did enjoy Dragon Age: Origins, but I'm sure it's better on the PC.
