I got invited to join a MUD recently, and I really want to like it, but I just don't get it. I used to spend hours playing Rogue, so I'm somewhat familiar with the whole dungeon game thing, but I'm having trouble with this. There don't seem to be any goals or story. So far all I understand is that it's a big huge board with lots of "rooms", and you walk around and kill stuff and get stuff. But what's the point? What's the objective? And more importantly, what do I need to understand to get good at it?
