GrandorCZ could have easily won that game if he's built some actual endgame stuff. If he didn't like superweapons he could have gone with nuke spam or Ultimatum+Scallop+Conch spam (creeping along the ocean floorbed to avoid superweapons) or Raven spam (spread out waves works well) or Funnelweb spam (20 Funnelwebs can last quite a long time against a DRP).
