As a Rumiko Takahashi fan I say that fans of Inu-Yasha (like me) should stay far far FAR away from this game. Sadly.
Difficulty: Boringly easy. I didn't know what the controls were and I beat the first 4 battles not even knowing the controls. It's pathetic.
Gameplay: Basically you get 1 or 2 characters. You both share the same lives. Every time ONE of you dies then you lose a life and so you need to decide whether or not they are worth it to have on your team. Basically the only way to win is to hope your enemy isn't using a ranged attacker. Every time they attack with a bow or what ever, you get stunned for a second. If you're by yourself against a ranged attacker you are screwed. They can hammer on you while you can't move. It's so horribly unbalanced. Only entertainment is in Multiplayer depending on if you know someone who wants to play. Also the tall players can't hit the short players very well and there isn't really any targetting. Me and another player tried to hit each other but kept missing for like 2 minutes cause of the controlls and how we were attacking.
Graphics: For it being Inu-Yasha it's ok. The graphics could of been MUCH better including CG animation for the specials etc... Only fans of the series will enjoy the graphics and not guarenteed to.
Sound: Voice actors from the show. Good sound. Nothing impressive. Sound is definately the highest point.
Value: You may play it a few times. Probably not. Horrible
Tilt: I only liked the multiplayer which was horribly lacking. Thus this score is low.
