Players invest themselves in the process, filling in details and suspending disbelief. Some users insist that the introduction of graphics would diminish rather than enhance MUDding. They stress that MUDding is a social rather than sensory experience. The MUD Environment Unlike the dynamic, continuous, visual spaces in most video games, the movement in the space of a text MUD is episodic. Often the spaces are separated from each other by directional links.
Users rely on memory to recall nearby spaces.
The MUD typically only presents a room's description when the player is in it. The effect is as though the user were tunneling through a solid to go from one space to another. And it's this interior quality that leads to spaces being called rooms. At times it's a claustrophobic world. For instance, users can't casually see distant views through windows or doors as they might in real life.
