Heh, same thing here. I can either study for a final that won't matter
very much next year anyway (I'm switching majors and this class won't
be required for the new major) or I can work on my project. I'd much
rather work on the project. :)

Hmm, interesting. I had initially considered treating mountains as
objects atop which maps can be placed, but heights assigned to maps
might work. The only drawback that I can think of is, I don't know
quite how to simulate slopes. The slopes wouldn't be very important
for the descriptions, but they would be needed to assign coordinates
to each location on the map. Without a slope, a mountain might be
represented by a map whose hight is much higher, without any
sloping to reach that height. (Of course, that would probably be the
case for objects, too.)

I was thinking of tying this into object size, maybe correlating it to
surface area, weather conditions, distance and the user's
eyesight. Since I'm designing a system which I want others to build
on, though, one of my aims is not to dictate a game designer's choices
of statistics. I may have some internal statistics such as strength
and perception, though these are more abstract. I.e. vehicles and such
can also possess strength; since maximum velocities may differ based
on terrain, the strength of something is merely how much energy it can
put forth. I may rename this to 'force', or something more
abstract. Then if someone wants to use the internal statistic for
their own games, it could tie into all pre-written systems.

I thought about that too. My thoughts are that processing power is
continuously becoming less expensive, and that it should be possible
for most game designers to afford reasonably fast
machines. Furthermore, I don't anticipate the platform becoming
insanely popular if I ever finish it, and most of the community will
probably be happy with older servers. (Besides, by the time I finish
it, 2 GHz boxes may be extremely popular. :)

Wow, I like this idea. Mind if I steal it? ;)

Seriously though, it's much better than my idea of coding in lots of
interactions. My only concern is with an object's descriptions: how
would you then describe the shovel head or the ashes once the shovel
burns? It may be possible to describe the ashes, since one pair of
ashes looks like another, but what if the person burns a rake instead?
You could probably tell the difference between a burned shovel head
and a burned rake head, but how would it be described? Would the
builder have to describe both the head and the pole?

No, not at all. The server isn't generating raw strings from
scratch. The user still writes descriptions in a markup language. The
markup language has tags which perform switches based on a large
number of variables which the user can expand upon. I.e. Something like:

<switch variable="daynight">
<case value="day">
<str>The sun shines brightly.</str>
</case>
<case value="night">
<str>The moon shines brightly.</str>
</case>
</switch>

In this case, daynight can either hold the value "day" or "night" and
is defined server-side. You could also have additional variables,
"timeofday" which could hold dawn, morning, afternoon, evening, night,
etc. It would even be possible to define game-specific variables. If, for
example, your setting had two moons, you could define a variable which
described the phase of both moons and tie that into the game
scheduler. The markup language would also be used for all messages, so
it would be possible to describe all actions differently based on any
factors. If, for example, you coded a black limousine, and coded it to
emit certain message events to those outside as it travels, during the
day its actions could describe it as a luxurious black limousine,
while at night it may appear as a sinister dark shadow.
