To clarify my post on page one,
I don't think the crew looks better gr aphically, or physics or anything like that.... it just looks more fun. And that's why I play games, to have fun.
Being able to drive anywhere in a huge open world is more appealing to me then driving set tracks over and over again. As much as I like doing time trials and ghosts, after a while it's not enough. That's why I liked test drive unlimited 2 so much. All of ibiza and Hawaii to explore. Races on tracks, point to point, various challenges, seeing people in your world online and challenging them to a race, or just driving around for fun both alone or with someone and chatting.
