XBOX Live on WP7

I have had a XBOX and an XBOX360 for the longest time.  While many of you might also have the XBOX360 and subscribes to XBOX Live, there are a few of you who has no idea what XBOX Live is except it's on your brand new WP7 phone.

In this article, I will attempt to explain to those of you who are confused about what XBOX Live is, what achievements are, what a gamertag is, when XBOX Live games are released and finally, the difference between games that a worth of a `XBOX Live` tag vs. games that do not. 

This article, however, will not recommend which XBOX Live game to buy or not buy, I am not reviewing all the titles and honestly, since everyone enjoys different types of games, having me reviewing games is pointless since ALL XBOX Live titles (on WP7 and on XBOX360) have trial mode and demo modes you can download and try out yourself.
