Tales of Graces F is within 2-3 weeks of release in Japan and a bunch more details are coming out. Looks like aside from just adding the epilogue and more abilities/hi-ougi/dungeons, they're attempting to offer lots of visual customizability to maybe make it more interesting to people who already played the Wii version? For example, special "attachment" accessories that show up on your character models (goofy hats, bags, plush Sophies, etc) some of which are pay DLC. More pay DLC in the form of crossover costumes for characters from Code Geass, Hatsune Miku, bla bla bla. You'd have to pay ME to use that crap but whatever. Also, free downloadable date-sensitive (i.e. holidays) chat sequences.
Anyways, seems like a ton of stuff in addition to the regular game, so I'm looking forward to a seriously packed release in a few weeks. Should be good.
Meanwhile, Radiant Mythology 3 website keeps updating every week or so with a new batch of characters revealed. I'm starting to wonder if every single Tales character ever is going to be playable.
