I agree. Many people saw the Enthusia trailer with skepticism, but, after some serious analysis, you can see a huge differential in Enthusia: the suspension work is very refined, even more than GT. That's what got me interested. Check the Quicktime trailer at
www.gametrailers.com and go frame-by-frame at the Mitsubishi Pajero/Montero jump... the suspension physics in excellent and car behaviour is great too. The same happens a few seconds later with the VW Touareg.
With the GT-R and RUF RGT, you can see the car body rolling over the wheels, suggesting an advanced suspension development.
Even if Enthusia is not THAT good, I'm gonna get it because of the off-road racing. That's something that could be considered by PD...
