In spending a fair bit of time with Forza 5, one of the biggest surprises for me was just how different the AI is compared to previous series titles. Turn 10's Drivatar AI system has a silly name, but it is legit, and it makes a huge difference in how races feel. Gone are the pre-programmed lines for AI cars to follow. They're replaced by cloud-fueled profiles, each containing the data of your friends, and each assigned to different AI cars in your races. This means that you're now racing against the tendencies of real people. Fellow Forza fans need to know that AI cars are no longer predictable, meaning that your old tricks won't work. This alone is a game changer!
