I just finished Halo: ODST. It’s a short experience (about 6 hours or so), but the atmosphere of it was really interesting. Nice music, too. I’d definitely recommend it at the Black Friday prices I’ve seen (30 bucks).
I like that it came with an “All the Halo multiplayer stuff” disc, too. I think that’ll probably just be the disc that sits in my Xbox if I’m not playing something else. You never know when you’ll want a little Halo Multiplayer 😀
