1) I'd allow you to name your character. 2) I'd have things actually matter, like I posted [url=http://www.bungie.net/en/Forum/Post/80726054/0/0/1]here[/url]. 3) I'd have something other than every single strike/raid ending with a giant boss that just shuffles from place to place while waves of minions hurl themselves at you. 4) I'd have community challenges, such as "if 3 million hive are killed in a 48 hour period, all users will be rewarded with <something>" 5) I'd plan my expansions to actually expand shit, like having a new planet, or a completely new area of a planet, and I'd have some sort of deep, meaningful back-story to explain the new planet or new area. 6) I'd plan on having some sort of cataclysmic event every year, something that we gear up for. If we pass the event, the world stays the same or gets better. If we fail the event (and it would be hard), the world would change for the worse. First event? Save and reactivate Rasputin. The community would have to band together to do a handful of multi-part tasks, including something raid related, and if, at the end, Rasputin survives, everyone's weapons would get a 100pt dmg buff. If we failed, and Rasputin was lost, the community would have to spend the next year dealing with random public events that spawned inside the tower while you're trying to turn in bounties and refill your ammo syncs. 7) I'd have the factions actually do something other than provide another vendor in the tower. And your faction alignment would matter, and would make both players and NPCs interact with you differently 8) I'd allow player trading of gear 9) I'd expand the classes a little, so that each class has more distinct advantages and drawbacks (just a personal preference, I think what we have today is serviceable) Those are just off the top of my head. There's a TON more that could be done to make this feel like a world where we're fighting a war, instead of just a game that has a grind.
