Hi,

most of the programs in this category use gm2/python/pygame, which does
not have gui (menu etc).

I don't know much about Object Pascal or FPC.  However it does work well
with gm2, the runtime checking and ease of producing a shared library is
appealing.

they are built from two components.  The command line text based
application written in Modula-2 and then the pygame front end which
interacts with the Modula-2 program using the pexpect module.

This allows traditional debugging of the AI command line program in
Modula-2.  Once this is complete - then the pygame front end is written
and the two are bolted together.

if you are interested I'll put the code into the download area?

very roughly 

 25000   lines of C
157000   lines of Modula-2  (including libraries).
 16000   grammar files.
