Stay far away from this if you hate Prince of Qin.
This is worse. Seal of Evil is like playing Prince of Qin part II in the year Prince of Qin was out. Which means, the graphics suck by 2006's standard, the gameplay is recycled and the translation again makes the ancient Chinese heroes sound like a dubbed 70's Jackie Chan movie.
If you like Diablo 2, which the game stall owners may psyche you about the similarities, then replay Diablo 2 with a new character. If you love Chinese fantasy martial-arts stuff, pick up Tai Chi. And if you really love hack'n'slash games like a no-brainer, try pillow fight with yourself, it's more rewarding.
