I haven't seen the videos, but I can tell you this. I love the Ferrari 333SP. And with that 333SP sideways in Forza, kind of reminds me of racing that Forza demo with the aids off (in fact, I can't remember if I had the aids on or off, but let's assume that I did have them on and just couldn't drive like crap). I've raced Laguna Seca in countless racing games. The look and feel of 'Seca in both games are pretty accurate. Laguna Seca really looked like the Laguna Seca I see on Speed Channel in Forza, so that's a plus for the XBOX-exclusive Forza. I think eveything was pretty accurate. The dreaded Corkscrew in Forza (and even GT4) is still just like Dale Earnhardt, an Intimidator. About the grass... I think I mentioned this in the thread when we seen our first look at Sears Point and Motegi. Whereas Laguna Seca in Forza has everything dusty and desert-like, Gran Turismo has things more dusty, but with more grass. Of course, I'm no pro to Laguna Seca. I think Forza kind of has it pretty much like what you'd probably find if you went to Laguna Seca RIGHT NOW. Gran Turismo 4 kind of has it in kind of a rather beautiful setting. I like Laguna Seca in both games, really.
I have full experience of AI from past GTs and the Forza demo. All I can say is, no one's perfect. By the way, nice to see the Spyker C8 in action. Muy bien y muy gracias, amigo.
