Silver is the free version of live, but you don't get as much as the gold version. You can get friends on silver and you can send messages, but you can't join into parties, and I think you can get stuff off of the marketplace. When it comes to games with multiplayer, you can't play online with other people.
there is a silver and a gold, so ,twice.
I believe Xbox360 Arcade is a part of Live. You can actually access Live at any point so long as you're connected but if you're on a silver subscription which, is unpaid then you are limited and don't have access to multi-player gaming and other features.
do you mean points, or the wireless connection?
it depends on what your into me personally i would get xbox360 live as i really enjoy that :P
Yes, but you will need a xbox360 live gold membership card to be able to play them online.
go to xbox LIVE marketplace and there is a huge list of downloads
That is a down grade.
XBOX Live.
i would tell the xbox360 makers. or maybe you entered the wrong code but rather then that i don't know
No.
its awsome.
You have to pay for xbox live.
