This game is much better than Vesperia and Xillia. Those who say it isn't never played.
First of all, the great battle system. It can't even be compared to that old outdated one in Vesperia and Xillia(and also abyss, symohonia, and other games of that team). The game is made by the original Tales of Phantasia team, which formed Team Destiny after, and their games are always the best, though, besides original Phantasia and Destiny - unlocalized up to Graces.
Then it comes the Characters, character development, and such. In Tales of Graces, character development is one of the best, if you ask me. In just the Childhood Arc(about 2 hours of gameplay or more), the character development went MUCH farther than in 3/4 Vesperia.
Then it's the story, and story development. The story is a great, dramatic story of bonds, friendship, selfless heroism and much more, and opens to the player in a well thought way with both events, skits and everything at all.After it its great soundtrack and voice acting(and I'm speaking about the japanese one).I won't comment the graphics, since it doesn't really matter, but I'll tell you that PS3 version, supporting 720p(no 1080, sorry, if it'll be in english version, it'll probably be upscale), looks much better.
