So I tried it a bit. The game definitely is big, game meaning world.
Look I know it's a demo, but the reviews were Spot on. The game really feels empty. All the open space, but yet not as explorable as you might think. Desert races and such are not really that fun as you dont really have any obstacles that can block you, so its basically put foot flat and steer. I would have loved a more technical, thinking-man's racing experienced.
