Primitive axes are made with a split/forked piece of wood and the head
jammed in the split. This is the type of axe more likely to be made by a
player lost in the woods, which I would think is a more likely reason for
someone to want to "make" an axe in the first place.
You are lost in the woods.
There is a piece of metal here.

It is an axehead. On the back you can read the words: "Forged by Chicago

Any kind of template system needs to be very robust and fairly fuzzy. I
like the idea of standardized sockets, and this would certainly give an,
er, industrial feel to the game. Can one really not fit a square peg in a
round hole? In addition to being able to build things in the game, making
non-standard or jury-rigged things would enhance this kind of template

But such an object could /act/ like a table - you could put things on top
of it, or seek shelter from the rain under it.

This is the computer playing dumb. I would append "one might call it
a table," to the description. It is now excessively verbose.

I would say you do, because you want the game to understand what you are
trying to do. If it doesn't recognize the idea of a table then objects
will never "fall off" the table. (Short of a ridiculous amount of "real"
physics, which in my opinion would detract more from the game in their
misapplication than they ever add in the rare case of an object behaving
"realistically" - an object falling off of a table.) Players have an
intuitive sense of function: pointy things are weapons, top-heavy things
can be pushed over. How can the game sense that which is obvious to the

- Swinging doors don't stay open.
- A curtain can act as a door.
- A window can be used as a door.
The function of these different "doors" is clear to the player, even when
the object description is poor. From the above, an unhinged door can be a
lot of fun for the admins: 'Well, today we got another 3 bug reports about
the broken door quest.'

In a very homogenous mud world (which is most of them) yes you can sleep
just about anywhere. Is this not absurd? But what is wrong with being
able to find a bed/comfortable place to sleep? A lake is not a good bed.
The street is not a good place to sleep. We need to be able to find that
functionality, or perhaps recognize its lack. Hmm, that is something to

Ok, so what function would the caveman attribute to the table? Probably a
good shelter from the rain. And the knight a computer? Something that
sparks and fizzes when you smash it. The destruction of objects is tied
into their perceived function as well, as the pieces may be used to build
something similar yet different - a tabletop to a door, curtains to a

This is the illusion of 3d: it is easier to make something look like an
object than to make it behave like an object. Building things
quickly loses its charm when the objects don't develop their own
behaviors. I have seen enough super-high-tech 3d game engines (object
oriented! with behaviors!) to say that this is a major problem, that
these simulations lack any kind of large commercial appeal.

This makes me wonder why weapons of mass destruction are taboo in muds.
