Yes
It depends. Some Xbox games need some sort of connection or something but some Xbox games can be played on Xbox360 but you dont get achievements.
Yeah, but you can't do Kinect(of course).
You don't need live to save games to the hard drive the game will simply ask you to create a new games save and off you go. If you have a memory card too the game will give you a choice of which device to save your game on.
Yes, they can be played on an Xbox 360. Just make sure you have a hard drive!
yes it can
Nope, Xbox360 games bought in the US will not work on an EU system.
no idea i recommend getting a new one
A Xbox360 is a console, the second after the first Xbox. You play Xbox360 games on it and I think you can download or buy a thing so you can play your Xbox games on it to.
yes you can but only if you have a hard drive
If you're asking if xbox360 is in Australia and can be played in Australia then yes. Otherwise I have no idea what you are asking.
Only normal Xbox games can be played on the original Xbox, original Xbox games can work on the Xbox 360 thought...
