I have a few questions about the XBOX.

1) If I buy a XBOX in Korea, would the XBOX work in America? If not why, and what would I need to do to make it work?
2) Is the 4gb enough or is 250gb a little safer. I heard you can expand the storage or something like that. I don't really know.
3) Could you use a disc bought from any country with a console bought from any country and would it still be compatible?
I'm new to this XBOX, gaming consoles thing so my "terms" might be a little off or wrong. Thanks.

I'm not sure, but you should try going either on the Xbox website, or going to a gams store and ask questions there. Sorry I couldn't help :P
