In a text adventure system, the game centres around a characters travel through a world. Each location has a description, which can add flavor and dramatic tension to a situation. Locations lead to other locations (let's call this an exit), which in turn leads to other locations. The player navigates through a world by typing commands (north, walk east, go south), and can also interact with 'objects' such as a door, a button, an item of treasure. Some objects can act as containers, and some can act as triggers for a certain event (key unlocks a door).
From this description, can you think of some suitable objects for a text-adventure gaming system?
Here's some objects that I thought of :
Room object
Exit object
"Real" objects (item object).
Player object
(Optionally) Character object (talking bear, goblin, wizard)
