Resonance of Fate is a game that will probably not receive too much attention, due to it's release so close to Final Fantasy XIII. But make no mistake, RoS is a stellar RPG, doing things very differently, and very well. To sum it up in a few words, imagine Valkyrie Profile mixed with Valkyria Chronicles and you've got a good idea of how the combat in this game works. And you will see a lot of combat in this game. It's fun but can be hard to grasp at first. When you get into it, however, it can be barrels of fun just ploughing through a random battle.
The world map is constructed like a sort of unlockable chessboard, requiring you to place hexagonal shapes on to a grid to proceed. It is a unique way of presentation, and is also quite fun.
If you're one of those who felt that FFXIII was too easy, this game will be right up your alley. it is very challenging at times, but it never feels too unfair.
The story takes a while to pick up, but from what I have seen so far, it is full of humorous moments and witty dialogue. You can choose to hear the dialogue in Japanese, (Thank goodness) or English. I prefer Japanese, but the English dub is actually quite good as well.
Looking for a challenging RPG that does things a bit different? Look no further than Resonance of Fate.
