If you can keep your monsters from dying too often you can assemble a strong force needed to win. There's no multi player option like Romance of the Three Kingdoms, which is too bad because it might be more fun then playing against the non-challenging AI, which sticks to a few set patterns that you'll figure out quickly. You definitely have to plan things out and have some foresight to be successful, which is most of the appeal in a stragegy game. As your monsters and Rune Knights level up, they can gain different classes that are more powerful and a change of pace. The story and translation is not good though, so don't expect much in this area.
Graphics are bland.
Fortunately you can turn this off. Sound is repetitive no matter what kindgom you choose, and is best forgotten. You'll find yourself turning it off soon into the game I'd imagine. Oh well, strategy games almost never have good sound so at least this isn't anything unexpected. Nice job, Atlus.
