Questions on the X-Box;

1. Can I play games from Japan and Europe on the X-Box, or are the softwares and hardware region specific like PS2?

2. Does the X-Box have a 5.1 audio output and can it support DTS?

3. My nephews need to play, too. But I heard that the controller was super duper large? Will it effect playability on people or kids who have small hands?

4. If I do buy the X-Box, Tony Hawk 3 will be a must buy. Just wondering, how good is Halo and which football game would be my best bet? (I like more action than management, a simplified interface as a user and would prefer the CPU to take control of other things)

Thanks for whomever would answer my basic questions.
