Great battle system. Challenging at times which is a good thing. Hilarious at many times. Casino is good for spare time.
The boss battles are long and mostly difficult(again, that's a good thing). There's a sweet mini-boss rush towards the end of the game(they're even harder than many of the actual bosses. The story itself is great and explains the origins of the God Hand and the Demon Hand. There's an arena that gets bigger as you go through the game. The arena features andvance gameplay and challenging boss rematches that allow you to get cash and unlock items in the shop. The things you can do aside from the story are great and addicting.
The only drawback is trying to play through the game a second time. You lose all of your upgrades and any purchased moves, but you do get new costumes and a poodle race mini-game. Overall it's just an excellent game and is worth anyone's time.
