Sounds like buyer's remorse. I got Kaze Kiri as a free, unsolicited CD-R from an ebay seller BITD (2002?). Having ever heard of it until then, I had no expectations and was pleasantly surprised. It may be repetitive, but the (ninja) action is fast, the controls are simple and responsive, and the music is rocking. I should probably play it again now that I have a modded XBOX and don't have to worry about ruining my hardware with CD-Rs.
