Been playing WWI since it first came out. The game has improved a lot over the years. Good job! To further improve it, please develop some additional tools to assist the players, e.g., a structured list of what pre-programmed production (not player-purchased), mobilization, and similar units are coming each turn (and where, exactly), for both sides. Another idea - when units retreat as a result of combat, keep their values visible to the opposing player for the rest of the current turn. As is now, you need to watch carefully each combat action to see what happened in case the enemy unit retreats, (and values go blank) so you can execute follow-up attacks appropriately.
