My implementation was pretty memory-stingy.  It was an ascii overhead system
so I didn't need a whole lot of information, but by adding a few kludges to
the stock room system I still had access to room flags and such, although in a
limited fashion.  My solution was to use descriptionless stock rooms as my
terrain models.  In other words, there was a plains room, a forest room, etc.
These terrain rooms were all in a dedicated zone.

I used a 200x200 short int array for the map, where each element was the vnum
of the room that represented the terrain type.  I added mapX and mapY
variables to the character and object structures.  If they're in zone X (the
terrain zone), they were logically located in the terrain room.  The CAN_SEE
macros were modified so you'd only see people in that room if they also shared
your coordinates.

This required changes to movement and communications code.  I think it took me
about 3 days to get the basics set up (very quick for me at the time) and it
had very little effect on memory.  I think I may even have a copy of the
pre-bugfixed code if you want examples.
