I bought my XBOX like a month ago, and I got Lost Planet, Fusion Frenzy 2 (auch, I really liked FF1), Halo, Assassins Creed and three gems that go by the name of Eternal Sonata, Blue Dragon and Castle Crashers.
I'll be getting Halo 2 and Halo 3 to run through it with my girlfriend, who has thus far never played shooters but really seemed to like Halo and its story. From there, I'll probably get Gears of War 1 and 2, then get ourselves some nice new casual Arcade title. I skipped Braid, I don't know why - it just didn't feel good after playing the demo.
For now, we're running through Blue Dragon simultaneously, trying to keep at an equal pace. We've sort of decided that after completing it, we'll go through the other Halo games (seeing 1 didn't really 'connect' to 2, but 2 & 3 are basically one continuing story) and then play Eternal Sonata in coop mode.
I really love Live Silver, with being able to watch trailers of new games from the screen, and downloading demos. Gold adds a little for me, as I'm more of a 'couch gamer', but I've lengthened my subscription anyway. At about $5 a month with a year subscription, it can't really bother me - I really think people complaining about the 'cost' are heavily exaggerating. I spend more on useless gizmo's per week than I spend on Gold per month.
Oh, and Marketplace is pretty good too. They should 'hire' movies through there, that would be a blast. Instead of going to the cinema, buying a DVD of a movie you've never seen, or hiring it through storm and rain, you'd just turn on your XBOX and select and watch the movie. Would make me visit the video Marketplace, which now feels a bit forced. The Game Marketplace is awesome - can really recommend Castle Crashers.
Yes, I love my 360.
