Sure, Project Gotham Racing 4 will have a slew of cars, online modes, and fancy weather effects. That's great, and we're all very excited. But the real reason why we'll be buying Project Gotham Racing 4 this October? The inclusion of Geometry Wars: Waves.
Like Geometry Wars: Retro Evolved in PGR 3, Waves will be playable on the virtual free standing arcade cabinet located in your garage. The title looks like it will play identical to previous Geometry Wars titles, but will contain new enemies and enemy patterns. Oh, and then there's the new music, which will likely haunt you for months.
Geometry Wars: Waves has not been announced as an Xbox LIVE Arcade title, and will only be available on the PGR 4 disc when it ships. Is Waves worth $59.99? I guess it depends on how big of a Geometry Wars fan you are; I heard it comes with a pretty decent racing game.
