Mutt's Adventure

Example 136
★★

Awarding points for visiting a room for the first time.

Suppose we want to reward the player the first time he reaches a given room. The "unvisited" attribute is useful for this: unlike such constructions as "going to a room for the first time", it doesn't develop false positives when the player has merely tried to go to the room in question. "Every turn when the player is in a room for the first time" is also unhelpful, because it continues to be true as long as the player is in a room on his first visit there.
