Both items (the controller and the TV) made us rethink the interface completely. For the PC we have a very "Windows™" like system. You can drag and drop things, rescale your menus, etc. Really the ultimate in PC game interfaces. That all gets thrown away on Xbox, and replaced with a system that uses the controller. It's superior to the PC interface in some ways. Overall it's actually faster to do things. The other thing with the interface is that it gets bigger on a TV, because of text size. This has caused us to change the art for the interface to make more of it transparent, so that the screen is not hidden.

We've also made the Xbox version default to playing in 3rd person mode. You can still play in 1st person on Xbox, but 3rd person has been spruced up and we're able to use the controller better. For instance, on the PC you hold shift to run. But on Xbox, there is no run button. You simply push the thumbstick further forward and you start to run instead of walk. Since running drains your fatigue, you don't want to always run and the ability to control this is much easier on Xbox with the thumbstick.

Xbox has caused us to rethink many things that we do and they've all benefited the game as a whole, regardless of platform. For example, making the interface more transparent, since both versions look much, much better now. Xbox has no virtual memory, something we use extensively on the PC, so we reworked some systems and now the PC version loads in a tenth of the time it did a few months ago.

I've also read many threads about "The Death of PC Gaming!" We all know that is silly, and there are things a PC does that a console will never do better. But if you're a PC fan you should broaden your horizons into consoles more. Because there are some amazing games coming out that you'll miss, and they do things that no PC game could ever do. Consoles have the one big advantage that the PC can never touch…they are all the same. We can tweak the movement and speeds because every person has the same controller. We can add certain visual effects because they all have the same processor and video chip. And they all work.

So which version is better? Depends on who you are. Do you like to play first person games with a mouse or do you like to slouch back on the sofa with a controller? What kind of premium do you place on graphics and performance? What kind of PC do you have and are you buying an Xbox?

They both offer a giant world for you to experience any way you want…but one of them only uses four buttons.
