Many role-playing games are in development. But do you remember ... "Eternal Sonata" (PS3/360)?
"Eternal Sonata" was no success for the developers. I think it's sad. It was not a long game, i know ... but I had played it 3 times: D It was pretty with great music and a good ending. The game was okay, i think.
"Eternal Sonata 2" by Namco Bandai? Or what do you think - will there ever be a second part?
By the way. An overview with new PS4-Jrpgs-announcements and a list can be found here - What JRPGs you would still like to watch? Write it there:
