Yes, they are all the same.
Yes it will.
A game bought for an Xbox will always work for an Xbox. Unfortunately, buying an Xbox 360 game will not work for a normal Xbox system. But most stores will give a full refund and/or a swap. Hope this helped.

As long as the game and the xbox has the same region encoding then yes you can
If you bought an xbox 360 game anywhere, it can play on any xbox. If You buy a game from somewhere that uses PAL ( it says if it is PAL on the top of the xbox 360 case ) then it will work on an xbox 360 from Europe. But if you buy a game from somewhere like USA, then it will not work as they use something else :)
Sorry, but No.
Yes Im almost 100% sure you can.
Both the game and the console have to be from the same region to be compatible.
Yes As Long As You Have A Gold Membership for xbox live
Unfortunately, you cant. If you look in the description of the game it will usually say "there are no refunds on this item"
you have to have the hdmi cable
It should, yes. Europe and Australia are usually considered as the same 'region' for the purposes of game lockout.
