Joystiq: "The problem with these cloud people, as I've come to call them, is that they're a bunch of assholes. In fact, I'm told that my Drivatar is evil incarnate as well, even though I try to drive with some modicum of politeness, taking my corners cleanly without using other cars as brake padding." [The author goes on to say that he likes the cloud AI feature specifically because of the unpredictability it offers, so he's not being negative]
Eurogamer: "In principle, it's a smart idea - while you're playing, your behaviour is recorded, assembled and then uploaded to the cloud, from which an avatar is seeded and competes on your behalf (and from which you can earn credits when not actively playing yourself). In practice, it's a backwards step, with erratic AI contributing to offline events that feel like an ill-mannered online scuffle where racing etiquette is thrown out the window.
Why have just the one braking point when you can have two? And why not have a quick dab of the brake in the middle of a straight? The unpredictable driving of others creates too many needless scraps - it's a good thing that Forza's rewind feature is intact, though it's a shame you have to put into use so many times because of the AI. The data that's in there is pooled from a good number of players, pulled from Turn 10 and Microsoft - so you'd have thought it'd be of a reasonable quality. There's the potential for it to improve over time, but right now the Xbox One's heavily touted cloud rains down a thunderstorm of idiocy."
