depends on the game
No but if you buy the game that is the same games as the 360 game you can play it.
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.
You can't. Xbox360 can only play Xbox360 games.
Well.....no. A big NO! Games for PC are on a different format than game for Xbox360... although there are games that are made for both PC and Xbox360.
put the xbox game in the 360
you could play any game
your game doesn't work... i guess
depends where and how much the games are worth.. (older the games less money they are worth)
Go to the game marketplace and then go to games click on indie and download
