Okay so I have an idea regarding ships! What if in-game guilds/clans (if they exist) could have a group ship? A sort of mothership that, according to the whims of the captain/clan leader, could orbit around certain planets as a sort of secondary base and refueling station. Floating in space is fairly easy on the graphics engine, so I assume the Xbox 360 version could support up to 16-20 players on board at once. What would be even cooler is if you could actually engage in space warfare as a team, one man piloting, and then many others at different stations. http://halo.bungie.net/News/content.aspx?cid=32237 In my mind it would be the coolest way to chill after kicking alien butt across the system, and would provide that warm fuzzy feeling of teamwork that the Elephants in Halo 3 did! TLDR: Multi-person ships for ultimate team-playing.
