Forza 3 modified and (to be honest,) ruined the brilliant formula presented in Forza 2. Now they rub salt int the wound by making us rebuy the entire game for the SLS, LFA and CCX, along with some other XBL pittances? I have no idea how they can do this without fixing the problems within the game right now. While I understand that this is largely to try and recruit as many Forza Faithful (indifferent of Top Gear affiliation) before the release of GT5, the presence of such glaring bugs within the game (broken interior dashboards, car/data disappearances, paint lighting issues, lack of drift smoke, rare graphical glitches) strongly has put myself and many others on their forums at odds with Turn10. My hope is that GT5 doesn't suffer from the same problems.

My history with Forza 3 is as follows: After the brilliance that was Forza 2, I pre-ordered and paid for the LCE. I bought the two car packs that actually interested me and then a couple of the others that went on sale as DotW. 920/1000 on the game. Then, the game steals all of my auctions and DLC cars from me one day in some freak occurrence and neither T10 nor MS could do anything about it. I lost millions as a result, losing over 10 million credits in LMP1 cars alone, not to mention my designs and storefront; everything was gone except my Season Play/Event List progress [read: I cannot get the tournament win bonuses anymore, which essentially double tournament earnings], and most non-DLC/Disc2 cars. That equated to a good 15 or so driving hours wasted, at least. This sick joke has gone on for long enough. 

I was planning to get rid of my Xbox thanks to the recent bump-up in Live and my subscription expires next March, coupled with the use of my Xbox solely for weekend MW2 with my friends and Forza 3 on occasion. This seals the deal. 

Peace, Microsoft. It's been good, from Forza 2 to MW2. You guys have just made one too many mistakes for my patronage.
