"Grey Goo is something worse than bad; it is mundane. Not so much a throwback as a bland crust, the heel of a loaf of bread left on a cutting board. It is a competent husk missing any vital organs. You can practically smell the Westwood coming off the feature list, which is hardly surprising given that developer Petroglyph includes a bunch of former Westwooders. Grey Goo has a lot of the trappings of those Westwood classics: simplicity, speed, streamlining, individual soldiers and tanks jostling each other as they swarm around in a big blob. But what you can’t smell is any sense of personality or joy."
