I'm not sure why I bothered to read this preview, if I walked into a game shop and saw a box with Forza 4 in black bold times new roman on a plain white cover with a price of roughly £40 and I could be sure it was a genuine product I would give that man roughly £40 for that box.
In fact I suggest an edit of this preview:
Forza 4: It's real. It's Forza, It's out sometime in October.
I think that would be enough for us all.
