Set two years after the events of Tales of Symphonia for the Nintendo GameCube, Dawn of the New World follows the journey of two new young heroes, Emil Castagnier and Marta Lualdi, as they seek to uncover the mystery of why their world has fallen into ruin. In their quest, their paths will cross with the original cast of Tales of Symphonia including Lloyd and Colette, as well as a summon spirit known as Ratatosk who claims to be the lord of all monsters.
If you played and enjoyed the gamecube original i'd give this one a look. It continues 2 years after where the gamecube one left off and starts with lots of plot twists.
Gameplay wise it's pretty much the same except you can now tame monsters and unison attacks work a bit differently. Roaming the world map has also been removed, it still exists as a visual but you now use a menu to travel the world; I think it's a welcome change.
I've played a lot of tales and I can only say i was a fan of two of them. The prequel to this game was on Gamecube and was alright. Tales of Vesperia is also pretty decent (ps3 and xbox360). This one I just couldn't get in to.
