Tried the demo, seems pretty good, though in terms of gameplay I'm not feeling it quite as much yet as with some of the excellent jungle / nature themed tracks in Pacific, but there too some tracks stood out way more than others (though the base level was still very good imho).
In some ways the destructive tracks feel like a step down from something like split second as well, in that you've got no control over any of that stuff - you can't use them to trigger game events strategically.
Other than that though, everything is butter smooth. Pacific Rift really distinguished itself in both the quality and the variation of the tracks. But I can definitely see that some people will favor Pacific Rift over this one, at least in terms of track/art. Really want to try the full game now, and yeah, definitely can see how 3D would help in this game.
