yes ps3 online and the new soon coming ps3 home
yea lol you play with other people around the world
No, but you can play with other players around the world if you have xbox live gold.
yes you can if you have xbox live but you cant play against people around the world like halo 3, you can only play system link which you dont need xbox live for anyway, all you need is a really long cable.
Sorry NO Is The Answer
They are the same but on Xbox Live games, you can go on Xbox Live (online) and play against other people from around the world. Xbox Games that do not have Live you cannot. But it is no big worry =]
No.
Like most gaming systems, the Xbox 360 is made to play original Xbox games too.
Xbox live will give you the best live gameplay where you can play with friends or just random people around the world. Also, xbox live will give you the latest content available for any game.
no but the other way around works
No! Forge World on Halo: Reach is completely free, provided you have the game and Xbox to play it on!
Technically, if you play a game on Xbox one that you played on the xbox 360 then once you start playing you will get all the achievements (basically like double gamerpoints) but not in-game progress*. *some games like happy wars and world of tanks etc. save in-game progress and achievements.
