Forza 5’s AI is “much more engaging than anything you’ll see in another racing game”
Also, you won’t need to be online to race against computer cars.
Forza 5’s biggest strength – well, aside from some quite unnecessarily magnificent visuals – could be its online Drivatars system, which creates an AI persona based on your playstyle and shares it with other users. The game’s “computer-controlled” cars are all, in fact, modelled on the behaviour of other human beings, and evolve over time as those human beings improve.
