Damn am I psyched for this game.
E3 09: New Features and Improvements Interview
As a Racing game fan, Forza 3 will be massive. Especially now that the game includes an in-car view, better damage psychics, with the possibility of cars rolling, and the all new video editing mode.
Forza already has a strong community of photographers, tuners and painters. The video edit mode will just add another dimension to the game and it's community.
I don't expect many people to be massively interested in the game, as I believe that I'm the only one that even still plays Forza 2. Forza 3 is one of my most anticipated games along with Arkham Asylum.
