Genewars

Once the inhabitants of Planet Earth finally got it together enough space travel-wise to explore outside the solar system, they discovered that there were three other races doing exactly the same: the sneaky, reptilian Saurians, the understandably uptight, nasally gifted Schnozzoids, and the curiously laid-back Bohemians. Each of these races being just as self-important, aggressive (except for the Bohemians) and intolerant as the Earthlings, it wasn't long before an intergalactic pagga of quite exceptional proportions kicked off. Advanced technologies previously used in the fast-food, mail-order gizmo and executive leisure industries were swiftly adapted into weaponry of astoundingly destructive properties, and the suzerainty of many hundred previously quiet, green planets was disputed in a most antisocial manner.
