some people want more achievements.
some people want more quests.
already there are notes left places with user created quests, and i think it would be really fun to be able to create badges to give to glitches that complete user-created quests.
i envision something like this: i decide i want to create a quest where you have to get into someone else's house and leave them a present, say a stack of something or a smelter or what-have you...
i make a "leaves gifts in someone else's house badge" and submit it to a game queue and once it's in there, any player who finds out about it (or maybe doesn't) and goes and does it gets the badge.
a mechanism like that could be REALLY fun. i do not know how hard it would be to implement, but my department has never been implementaton. my department has always been thinking up wacky ideas.
