Halo

I don't think I want to play: just don't have the time to get immersed right now, and I feel like if I was going to play, I'd want to be more experienced so I can enjoy it, rather than feeling like it's a frustrating learning experience. But I dipped into some very basic reading about the series since rumors of a movie are floating again, and I was wondering if any of y'all had read the books. Are they worth it? Will they give me a sense of Halo's universe and mythology in a way that won't feel flat? If so, let me know. I may give them a try.
