The video editor looks awesome, all the trailers were made in it which means it has some really powerful tools in it. However I'm never any good at stuff like that so probably would never use it. Good that its there though and you can share HD video online. The painting tool is also excellent in Forza 2 and some of the custom paint jobs are stunning

All I really care about is the drive though, which is top notch as there physics engine runs at 360 FPS and the car modelling is spot on.
