How Much is Xbox Live? is It Easy to Set Up? is It Worth It?

It depends. Silver membership is free, and it has everything Gold has except some game parts (like multiplayer and early demos). Gold is $50 a year, and sometimes you can get an extra month out of that too (if you buy the code from the right place). If have internet faster than 1mb/s, then its worth it (multiplayer is really good on Live, much better than the playstation Network multiplayer); if not, then just join Silver.

Suggestion:

It's £40 a year or £15 for 3 months or £5 a month. It's very easy to set up but you get a month free so try it out first to see if you think it's worth it
