If any of you have played Geometry Wars from the Xbox Live Marketplace, than you can relate to my elation. If those lighting effects could get any more dynamic, my eyes would develop cavities from the potent eye candy. That stuff is bad as hell and it's only about $7!!!(400 Microsoft Points). It also wields impressive and excessively fun gameplay especially for an arcade game. A MUST BUY if you have an Xbox 360 and Xbox Live.
