Seanspeed, we've had lengthy debates on fm.net about Race Pro in the past, and I respect you and your opinions.
I know my opinion has no bearing on how you feel about Turn 10 or the game. I love Forza too, and you know I'm a race replica painting addict/whore. I love mimicking the motorsports I follow through the racing, mostly through custom multi-class lobbies. I also know I'm coming off as sour grapes about this so far, but I am still looking forward to it and just hoped they'd acknowledge their tried and true fan base a bit more.
Granted they have in many ways, i.e. the car list, brining back car clubs, importing vinyl groups, re-working the cockpits, improving the lighting and graphics, etc.
Since you brought it up, if I were in charge of development, I'd keep the starting car list somewhat simlar to 3's, adding new cars down the line via DLC.
I'd listen to the fans and put back in some FM1 tracks. I know for a fact they worked on Blue Mountains for fm2 before it got cut. NY Long might be a quicker addition since the environment assest in already in.
I'd listen to the real world track requests and put resources towards creating Spa and/or Bathurst. I'd update Silverstone, and keep the old layouts like Shift did.
I'd make more use of the ALMS license with a few more tracks if time permittted before release, or offer one or two as DLC. I'd at least update the liveries to the 2010 season, and maybe have the 2011 season cars and liveries as a DLC pack in the future.
I would have taken a page from Race Pro or Shift and added some well needed track texture and bumps to all of the courses, so they aren't all glass smooth.
I would have saved time but not including a Kinect arcade mode. I would not have spent a lengthy ammount of time on another fictional mountain track since Ladera, Iberian, and Camino Viejo are similar.
People want variety, and aside from the car collector othergame5 mentality some have, most would prefer it to be in the form of track variation. I would have put more focus on that.
But I understand Turn 10's goals, make the game appeal to many markets, and that both makes Forza fantastic and hampers it in specific areas at the same time. It's so vast it appeals to casuals, online racers, hotlappers, drifters, motorsport series fans, painters, photographers, and general car nuts. Add in the new Kinect driving mode and they'll possible gain another demographic.
All of this is a big undertaking for a 2 year cycle, and like you said, you can't have it all. Or please everyone.
