You might like Live a Live if you want a JRPG. Otherwise, The World ends With You is a gamr that overlays a fantasy world over a seemingly 'normal' setting with a very unique art style. There are versions for different platforms but if you decide to play it you absolutely need to have a (3)DS
Thanks for checking! I will update the post.
