I got one, it rocks. You should get one too. As soon as I figure out the whole online thing, I have to go around finding people to 'community' with, or something. You can do oodles of stuff with this thing straight out of the box. You can even get online and start loosing badly to lots of other people.
Within nanoseconds (the plastic bags in the package hadn't even finished fluttering to the floor) you are downloading demos, and being thrashed by other people all over the world. Astounding. I can't tell you the game I purchased with it, as it's so totally uncool and shallow.
It comes with a free month of the full online service. You don't have to do anything, it just says "Oo you qualify, wanna try it?". The one that comes with it, does most things except the actual online gaming side. I used my already established hotmail address to sign up and my Xbox 360 already knew lots about me.
I don't know if putting your gamer tag up online is a good thing to do, but if it's no hassle then I am all over that one. It even comes with a headset to do your trash talkin' thang if you are so inclined. I just left it off while being left in the dust, figuring out what to press.
What to get next is the thing. You are presented with LOTS of chances to buy online points (some sort of currency) for different games or graphical aspects to the front end navigation wotsit. It was odd that I was there for quite a time before I even had to think about popping in the game I had purchased with it, as there was so much to tinker with.
As for the gameplay side of it. Luvverly.
