Jordan Golson: "Even better, they drive like specific humans: Every flesh and blood player gets a Drivatar of himself that learns from him and drives like he does. If your big sister isn’t online, you can play the digital version of her instead. (A separate version of Horizon 2, without Drivatars, will also be released on Xbox 360.)
So even if you’re the only human in a race, you’ll have a diverse set of opponents based on your online friends and other players. Some will be aggressive, smashing into other cars and taking every shortcut possible, while others are more likely to jump out of the way if you drive at them, or use extreme caution heading into corners. Sometimes they’ll just make mistakes, as people do, taking a corner too fast and spinning out, or crashing into oncoming traffic. The single-player mode is awfully close to playing with real people, and it’s a delight."
