I like Halo reach, ODST, and Wars because they show the war through someone else's eyes. You get to see what else is happening besides Master Chief being assume. Maybe a cool game would be Halo: Ghost of Onyx, where you play as some of the main spartans. It sort of happened before with Halo: Contact Harvest and Halo: The Fall of Reach. I not saying that the game would e the exactly the same, in fact it might be the same setting but from diffrent part of Onyx. I just saying it would be a nice idea for a game. It could be one of the best or worst game because most people like the Ghost of Onyx book the most. If it was made I hope you could play as Fred.
Wrong part of the forum dude. Anyways it's a good idea I guess since the only time your not master chief, your the arbiter or an odst. I'm also interested in the structures described in the book.
