So when drafting big OP's such as for the Halo 3 thread, I start out just outlining the topics I need to hit. My goal is to succinctly summarize every feature and then link to the primary info source. With Reach, my goal is to really improve the organization and make it cleaner than the Halo 3 thread, streamlining the layout (heavy use of thumbnails for large images, etc.) It's quickly becoming an intimidating task for Reach.
Features | Matchmaking | Loadouts | The Arena (Personal Rank, Seasons) | Commendations | Credit (cR) System | Armor Customization | Spartans vs. Elites | Active Roster | Veto System
And that's without the lists of maps, game types, weapons, armor abilities and other stuff that needs to go in (not to mention any other features that make it in, such as screenshots, file sharing and saved films). Trying to sum it up, it finally dawned on me why it's all been rolled out so slowly: there's a shitton of content in this Beta. The OP is going to be as big as Halo 3's retail release.
