Thus comes the contradiction.  Sure, poor areas can't afford system patrol
boats, but why should they have to?  The system is poor.  There's nothing
to steal.  Why would honest merchants come to such a place, unless it was
some sort of prearranged meeting (which sounds kind of suspicious)?  Even
under those circumstances, it would be nearly impossible for pirates to
know that there was a fat merchant ship in a backwater system unless they
had some kind of intelligence...

One of the other problems of pirate ops - due to the lack of any 
interstellar communications faster than ships, it's hard to get 
intelligence to a pirate in time for him to do anything about it.

Of course, other people have these communication lag problems
as well. If the captain of the _Argos Ascendant_ has to arrange 
a rendezvous with the captain of the _Mighty Joe_ to transfer 
a highly valuable smuggled cargo, the message has to get from
one to the other. If an agent with pirate contacts overhears the 
message, he may have time to get a corsair hidden there 
beforehand.

As for poor or low-tech worlds having little to steal, I agree (to a point).
Thus being a pirate is more challenging than simply jumping to any
world with a certain UPP and lying in wait, which is as it should be - 
_Citizens of the Imperium_ gives some pretty tough numbers for
Pirate success & survival, if I recall correctly.

My view of the formation of rocky (terrestrial) planets is that it occurs
too close to the star for ices to still exist, so the grains are (mostly)
solid minerals. This is usually cited as the distinction between
rocky-planet formation and gas giants, which form out in the edge
where enough ice is available for accretion to happen rapidly.
If you have a specific reference indicating otherwise I'd like to see

A sensible approach to radio rules would be to have radio ranges on a
log scale; one could then get the range at which two radios could
communicate by adding one's "recieve" strength to the others
"transmit" strength. (Not unlike the T4/DSR sensor rules.)

IMTU you have to pass through systems, you can't jump to empty
hexes.  So, if ships from System A wants to trade with System E
several parsecs away, they may have to pass through Systems B, C and
D to get there.  If these systems are poor, then the ships may only
stop in order to refuel, not to trade.  They might refuel at lonely
gas giants or backwater clearings.  Of course, having some kind of
intelligence would be, more or less, required to know where and when
to lie in wait.  ;->

Sorry for taking the private, but "Mistress Tiamat."  Just curious, is this
in an AD&D game or a r/l title you use amongst close friends??

Well live and learn!  This list is truly educational :^)

I must admit, the majority of Goth-gamers (I'm not a Goth, but Goth
friendly... with many such friends) I know are into AD&D or the various
White Wolf products in majority, not heard of any into sci-fi other than a
few who play cyber-punk like games??

I've got 'Web of Angels' and 'The Final Reflection' and I've read "How Much For Just The Planet?'.  I also have 2 copies of the JTAS issue with 'Road Show' in it.

Don't I feel a bit of a goose.  Heheheheh.

This was off topic so I wanted to send it private.  I am truly curious to
the "Mistress" part as I know a handful of Goths locally that play fantasy
games and use titles such as "Mistress" and "Master" in r/l and I was
seeking to find how common this is (it would have been my next question
depending on the answer -- I also know non-gamers that use these titles to).

So now it's public, can anyone else answer this question also?

Subject: Planetology 102 Part 12 (last)

11. Conclusion.
     At the beginning, I also promised a summary of how small
differences in solar system composition could produce radical
differences in the character of planets.  Even though prediction is
risky and I could well be overlooking some important effect, here are 
some possibilities.
     In Sol system, abundances of magnesium, iron, and silicon in
particular are so nearly balanced that differences of only a few
percent can make a significant difference in the size and
composition of the core, mantle, and crust of planets.
     Larger size, thick crusts, thick mantle, and less volcanic
activity all mean slower cooling, so volcanic activity should
last longer. Smaller size, thin crusts, thin mantle, and more
volcanic activity mean faster cooling. Smaller cores may mean 
weaker planetary magnetic fields.
   In magnesium rich system, magnesium should tend to displace
iron from the ferromagnesian silicates, and may produce larger
cores and more free iron in the system. In magnesium poor
systems, mantle composition will shift to include more iron, at
the expense of the cores, and may also mean more free silica, which would
concentrate in the crust.  Iron rich systems may put excess iron
in the cores rather than than displace magnesium; iron poor systems
ought take it from the cores first. These differences will prabably show up
in the asteroid belt as well. Silicon rich systems should have thicker
mantles and crusts. Silicate and aluminosilicate crusts are good
insulators, so perhaps less volcanic activity, more violent when it does
occur. Volcanic activity might be concentrated in hot spots or cracks,
with less mobility of tectonic plates. Silicon poor systems
should force more iron to the core, with a thinner mantle and
crust. These would have more but gentler tectonic activty, with
more and more mobile tectonic plates.
     High sulfur means probably more of it remaining in the crust
and mantle. Life should still be possible, but the planet may be
inhospitable to humans. Low sulfur may mean life has a harder
time getting started.  Aluminum-rich systems ought to have thicker
crusts; there isn't enough of it to affect the mantle much.
Aluminum-poor systems can be expected to have thin crusts, much
like those that are silicon-poor, and will probably see more
natural calcium and sodium silicates.
     Differences in calcium and sodium will have their most
visible effects in the composition of the sedimentary class of
rocks, and in the composition and salt balance of oceans.
Terrestrial life is highly sensitive to the balance of salts in
body fluids, which in most cases is rather similar to that in
terrestrial seawater. On a world with different mineral
proportions, terran transplants (including humans) could fare
very poorly except in limited areas. 

   These top fifteen elements pretty much control the composition and 
character of planets in this neigborhood of the galaxy; the 
remainder add variety and detail. There may be other regions 
that are richer in the heavier metallic elements; certainly some
are poorer in the rock formers. But this is as far as I had 
planned to go in this series, and I will save discussion of other 
elements for perhaps a later time.

It's also generated by geological processes. The less oxygen and
more hydrogen in the environment, the less CO2 and more CO you
find. It appears in volcanic gases and may be quite a bit more
common on geologically young worlds.

The halogens are not abundant enough to form much of these in
nature. Unlike several of these compounds, the halogenated
hydrocarbons are thermodynamically stable, at least in the
absence of oxygen. It may be that their salts with alkali metals
are more stable, but anything bacteria can make, higher life
forms can concievably make as well.

     Two more that have to be continually generated by some
industrial, biological, or geological process. Of these, cyanide
looks like the better bet, and again, in nature it will appear
mostly on worlds without much free oxygen.
