At the current time there are no plans for a Moshi Monsters Xbox game.
There is a huge game list for games that can be played on either the Xbox or the Xbox 360. All most all games now days play on either.
No that is why it is called a PSP game and not a Xbox 360 game
Halo3 and Call of Duty games are closely trailing behind
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.
Yes
I say the best game would be Halo since Halo can be only played on Xbox.
Yes. Most do.
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.
all can but most you need to manually update your Xbox the halo games and be played on Xbox 360
