I would like thank everyone who replied to my question.  Here is a summary
of what I found:

1. There are various LaTeX macro packages for drawing trees that do some
   of things I want, but not all.

   TreeTeX at ftp.uni-stuttgart.de in
   soft/tex/latex-style-unsupported/TREETEX

   Tree macros by Emma Pease at csli.stanford.edu in pub/TeXfiles

   Tree program by Greg Lee at blackbox.hacc.washington.edu (128.95.200.1)
   in pub/msdos/tree.zip  (Note: this is a preprocessor)

   nodeedge.shar at sun.soe.clarkson.edu in
   pub/tex/latex-style/ecl (Note: this also needs the epic & the eepic
   macro packages)

   In general, you can browse through D. Jones' tex-index archive of TeX
   and LaTeX macros.  This is available at niord.shsu.edu in
   [ANONYMOUS.TEX.TEX-INDEX]

2. I was also informed of a couple of packages which are quite general
   programs for drawing figures and may well be able to generate trees
   (I haven't tried either of them yet) with some additional effort.

   PSTRICKS, by Tim Van Zandt (tvz@Princeton.Edu).  This is a TeX front
   end for generating postscript graphics, i.e., a set of TeX macros will
   generate the ps file for you.

   MFPIC, by Thomas Leatham (leathum@griggs.dartmouth.edu).  This is a
   TeX front end for generating metafont graphics.

   Both the packages are available at niord.shsu.edu.

Once again, my sincere thanks to everyone who replied.  Unfortunately, it
seems that there is no royal road to drawing game trees.
