Yes not that bad sales but after playing the demo, I wonder why it didin't do as much as games like Devil May Cry 1 did on Ps2 time..

It got perfect score from Famitsu..

It is puplished by Sega and Devil May Cry makers made it = should mean much in Japan.

It was released at holidays..

It has hot chick as main character..

Very weird...I was expecting much from this.
