My Driving Force Pro arrived yesterday and I just got my copy of GT4 (Japanese)...played it at lunch in our main conference room with wheel mounted on a little table (took me nearly a half-an-hour trying to configure the wheel because I didn't realize the power strip I had plugged it into wasn't plugged in). Got to view it upon our 50" Sony plasma HDTV...480p at first, then in 1080i. WOW! 1080i is super crisp (almost too much so since there's no anti-aliasing)!
After one lap of driving the Takata Dome NSX around the Nurburgring Nordschleife course, I was sweating bullets...the wheel at full force makes you work really hard! I also took a crack at Infineon in an NSX (my NSXPO experience gave me a good line to follow), Laguna Seca in an S2000 (man, I kept breaking the rear loose), the Cathedral Rocks rally course in a WRX STI (I hung with the AI car for most of my first lap...but damn is rally a lot of work with the wheel), and then let my coworkers try the wheel. I think several of them will soon be placing orders on the wheel...it's THAT good.
I love the wheel. I love the game. Must play more.
I won't be playing it much at home since I don't have a Japanese or modded American PS2. Plus, I definitely need to find a little table for mounting the wheel.
I'm also impressed how the pedals didn't move away from me...the little carpet catch thing works surprisingly well!
