Playing games on Live on the 360 is mostly the same experience
as on the Xbox as far as gameplay goes. What is different
is that now you can chat with your friends anywhere and
everywhere even if you are playing different games and the
social aspect as a whole has been kicked up about a hundred
notches for the 360. Also, the gamer profile and gamerscore
that you build up as you earn achievements in games is something
that you are going to want to show off to people. This will
in turn increase the replay value of all of the Xbox 360
games because you’ll want to earn as many gamerscore points
as possible. Whether in single player or multiplayer, you
are always connected with your friends as well as with the
entire community through the gamer profile. It all is very
slick and works very well.
