Kinect was a huge boon to us as a creative team - to start exploring that vision. So we came up with the Autovista mode where you can move around the car, open the doors with your hands, accompanied by some of Jeremy Clarkson's trademark wit . that's a big part of the game. As well as Kinect head-tracking, we have Kinect Voice to navigate the UI and, of course, you can sit on the coach and play with your kids using Kinect driving. So innovation across the entire product has formed the personality of the game.

Talking about the cars themselves, how do you decide on your roster for each game? Do you go with team favourites, or fan requests, or what's hot at the moment?

For the first time, I would say yes - and it's because of Autovista. Honestly, that's the first time they've said "this is crazy!". They want to show it to their board of directors. The idea of seeing the car on a giant projector and being able to walk around it via Kinect, that has definitely got different departments within these companies interested.

does. We look at magazines such as Road and Track and Car and Driver, and we see what their test results are.

Well, in Forza - especially in Forza 4 - we give you multiple gift cars to choose from, not just at the beginning, but at every level. In the past we'd give you one gift car, now you get an option. We've selected those cars based on telling different automotive stories to people. So when you start off the game, you might have a Ford Ka or a small Citroen or a Chevy Spark, and those are great starter cars, because they're not fast enough to get you in to a lot of trouble. You need to work your way up to a Subaru STI or a BMW M3. I don't mean to be insulting, but novice drivers tend to over-estimate their driving abilities. They'll say, "I've played a lot of these games, I'm an expert!", and they'll select simulation steering, no ABS, manual gears, they spin out they hit a wall and then they go "That's not real". Well, yeah actually that happened because it's real. It's just like, if I took you to the track, I wouldn't want to turn off the traction control on a Ferrari 599 GTO - none of us should. Jeremy Clarkson did and said that the car was undriveable!
