@Kastrenzo, your Reach analogy is interesting. It's been a while since I've read the relevant books, but the thing is, the Fall of Reach was something that was already planned out - If I remember, it originally happened in a matter of days. I haven't paid attention to the dates in Reach, but supposedly the game takes place over two or three weeks, which a lot of people have criticized as a horrific break of canon to insert a story about a set of characters nobody cared about because they didn't previously exist and, honestly, weren't particularly well developed and were commonly thought to be killed off in pretty moronic ways.
