You seem to have taken what I've said completely out of context.
What that statement means to me is to handle the work by the object
with the data, not the other side.  Which is where you seem to be
going with this.

Yes, that would be amazingly ugly, I actually use a display(Token
ch) method.  With the level of abstraction that I'm using it'd be
impossible to get away with that level of detail.  Yes, I do have
several methods setup to retrieve/set data as you mentioned.
Actually the Room class implements a whole heirarchy of methods from
interfaces to handle things like containing creatures.

In this case, display handles all the dirty work, etc... it takes
the data directly and outputs it.  By simply using get/set methods,
you're just adding object overhead to a data structure without a
major gain, unless you have a variety of things to do in order to
modify those values.  I use alot of get/set methods, but I have a
wide variety of other methods to handle specific tasks that are
related directly to the data.
