sorry but i dont think so you need a hard drive :)
Yes, but some games, like Halo 3 will not let you play co-op campaign through xbox live and will not let you use theater.
xbox live play against friends and sky and memory and games to play
yes you can Evan get gta sa
Yes. You have to have a memory card or the last 360 your gamertag was on had to be an arcade version. If you have a memory card, simply go to the last xbox it was on. The look up the gamertag by going to the hard drive's memory, then gamerprofiles. There will be 2 options, delete or move. click move then move it to the MU. If you only have a hard drive you can move it the same exact way but it has to be on an xbox arcade system because these have built in memory units unlike the other 360s.
You only need to buy Xbox live if you want to play online.
yes u will need to have a chip/memory card in the Xbox 360 to play copied games
plug in console, buy card, play
No, but you need internet connection.
if you have xbox live, u can play any multiplayer
Xbox Live does not take up memory unless you download things. This I am positive of.
Yes, but if you have a memory card it should be fine.
No, in order to play on Xbox Live over the internet, regardless of ISP, you are required to have an Xbox Live Gold membership, or else you cannot play Xbox nor Xbox 360 games over the internet.
