The last installment I finished was most wanted. So I'm 2 titles behind, I haven't played Carbon and Pro Street. I installed the old one, NFS Underground since for me this is the most difficult NFS I've ever played. Traffic is so annoying and the AI racers are so damn good and fast, it's unbelievable how the AI makes the impossible high speed cornering!!! And the greatest reason why I reinstalled (I intend to finish it to NFSU2, NFSMW and to Carbon) is because I just bought my Logitech MOMO racing wheel. Force feedback crazy!!! And you can feel the slightest texture on the road, the softest bump on your rear and eveything in between. Makes the whole experience all worth it to start over again..! I figured, what's a racing game without a steering wheel!?
