Very good!
But there are a few problems I refuse to overlook. One is the lack of music. This game felt boring, just moving from town to town, with no sounds except clinking and clanging and people going, "Ugh!" Another thing I didn't like was the difficulty curve. The game was hardest in the beginning, and then it got easier, and then finally, effortless. Money is too easily acquired, and once I captured Nagoya and got Shogun Ghosts, I could just sit back and watch while they got one-hit kills on everything. Then there was the bad English and spelling. It's shuriken, not suriken. The last thing was the obvious lack of historical consistency with the equipment and tactics used by different areas of the world. For example, the Great Trade Empire seemed like it was supposed to be Rome, and so for all intents and purposes, to most players, it was, in fact, Rome. And you had their troops on horses. Romans sucked at horse riding. Only the troops they used from other countries that they conquered and a very few specially trained full-blooded Romans rode horses. They also did NOT use dual weapons, two-handed swords, or maces or axes. They used shortswords that were quick, efficient, and allowed for the use of a shield. And gold is a terrible material to make armor and weapons with. It would dent and break. Another thing is that you made it seem as though ninja were actually troops used by the empire. They were actually rebels, fighting AGAINST the empire and the samurai. Oh, and nobody would ever go into a pitched battle with a plain staff. A naginata, sure. A staff, hell no.
Even though it may seem I hate this game, I actually really like it. But I won't ignore the problems that take so much away from a promising game. Your overall grade is 70%. That isn't far from the dreadful D's. Try to do a little better next time.
