Anyone who plays Halo for more than the multiplayer (yes, that is possible) knows that there are other ways to explore the extremely long and convoluted storyline. One of these ways are the novels written by Eric Nylund, Karen Traviss, and William C. Dietz. Dietz wrote the novel Halo: The Flood, which is an expanded tie-in to Halo Combat Evolved. Nylund covered the Fall of Reach, the events between Halo CE and Halo 2, and even those during the events of Halo 3 that didn't involve the actual Halo 3 storyline.
That said, Halo 2 and Halo 3 are left out of the spectrum. I want to fix that by writing an equally detailed novella of Halo 2, and maybe later Halo 3. Even novellas of Halo Wars, Reach, ODST, and 4, with Spartan Ops accompanying. Note: These would not be official attempts at Halo merchandise, just fan-driven fun projects.
I have already started with the intentions of mixing the ODST story with the Halo 2 one. And, admittedly, it didn't work well. So, I would like your kind input. Should I continue writing a massive and painfully slow novel with both in them, or split them into two different books that flow much faster? Thank you for your time.
