How about implementing a help system? It would comprise of a window
with a
menu (with entries Units, Terrain, maybe some general game information,
Combat, ...) and a submenu for each menu entry (or just some entries pop
out). This would almost certainly raise information accesibility because
reading 'man crimson' is a step further than just kicking in the game
and
selecting Game Info or Help or whatever...
A full-blown help system is a lot of work, and while I don't want to
rule it out for the future I don't want to tackle it right now. Anyway,
whether we create a help system or just a terrain info dialog (which
might be integrated into the help system later on), we need to answer
very much the same questions: what, where, and how.
