For Sure Every Game On XbOX Has Xbox Live
XBOX Live is not a game console. It's a online game service for the XBOX 360.
For halo 3: Plug in a ethernet cord into the internet/ethernet spot in the back of your 360. Plug the other end of the cord into the other 360. Start up a custom game with the Game Setting (I think). Set that as System link instead of xbox live or Local. Sign in controllers and enjoy.
XBOX Live is not its own game system. XBOX Live is an online gaming and content delivery service that the XBOX 360 game system uses.
There is no "The Xbox Live", Xbox live is simply a pay-to-play game service where you can play Xbox 360 games online. It depends on the game if you can play it online or not, the game's box should on the back say if it can be played online.
I don't think that you can play an original Xbox game on an Xbox 360 live. But some games from the old xbox you can play on Xbox 360.
You can not play DeadFrontier on xbox live, the game is stricly a computer game.
No, Xbox Live is Microsoft's content and community service. You do not need Xbox Live in order to play any Xbox game.
Xbox Live gold is a way of getting xbox xbox live on your xbox. With xbox you can buy games, download gamer picturess, all of that stuff. Xbox Live gold is not a game.
