While we are on the topic of S30's in videogames, i've played Auto Modelista as well as Tokyo Extreme acer, the sequel, Zero, and all the japanese versions (Shutoku Hiway Battle). I highly recomend the first 2 games for Sega Dreamcast. The PS2 version (Tokyo Extreme Racer Zero) kinda sucked, the controls were all wierd....
A few days ago i came across Wangan Midnight at the arcade, and i have to say it is by far the coolest racing game i've ever played in my life... cruising the Tokyo wangan route in an R34 GTR at over 300kph, racing the famous S30 twin turbo... it just dosn't get better...
