Extremely good game. Pretty good story, banger music, deep complex battle system. Amazing cinematic skills. Despite the complexity of the system, it naturally flows.
Levels mean nothing much in this game. It is all about how you set the Dais(battle effects), plus equipment. Then enemy position, attack range, etc.
Every step should be taken into consideration. Most battles are like a mini dungeon. It uses semi-turn based. Meaning you can free roam, then engage in a turn based action-combo system.
