The fucking graphics and handling are awesome. Theres only six tracks, with multiple variations as per usual (long/short/reverse), but there are over 60 cars to choose from.
The online mode seems a little flawed right now, but hopefully they will fix all the bugs (its says it wont penalise people for collisions if the other person is driving eratically, but then penalises you if someone spins out and spears into the side of your car...dumb).
The fact its only a fraction of the cost of a full priced game, and doesnt involve having to do stupid licence tests like the last prologue game, makes it worth either buying or downloading!
From what I can gather, the UK version has some extra features over the Jap version that was released last year, but I dunno about the US version!
