Ive played it, and enjoyed it, but i would say, wait for GT4 itself to come out, but this is a good game in itself, super good graphics, super good car detail, and super good track and crowd detail. Probably the best looking driving game ive ever seen. But is it worth paying all that money for this game, as another reveiwer said, illd save my pennies and buy GT4 as soon as it came out.
Also, this game features some new circuits, and some new cars by makers such as McLaren :D. Real life tracks like the Fuji Speedway. Also the driving school is really good, which should have you ready to tackle GT4 when it hits the shelves. also the range of cars on just this taster, is big enough to satisfy me, and probably some other gamers out there.
