MUDs can certainly be aesccud of bloat but that was one of the things I tried to keep to a minimum in our games by teaching better writing skills. Walls of text are walls of text whether they're in emails or legal documents or text RPGs.I'd like to build a graphic game that continually inserts new content into old territory to keep society fairly centered while adding real estate intelligently; that doesn't mean it's a small world, but a world set up so that social hubs are never too far from anyone's reach. This is probably because I can't stand taking 10 minutes to cross a valley just to retrieve an herb or fish, or living in an empty city because everyone else has moved to higher ground.
