About the param in the file GlobalDefinesAlt.xml my supposition :
- DCM_BATTLE_EFFECTS : If set to 0 you don't have anymore the fog of war graphical effects nor the gameplay effects (food and moving).
- DCM_FIGHTER_ENGAGE : If set to 0 you don't have anymore for airplane fighters the attack option to engage enemy airplanes.
- DCM_RANGE_BOMBARD : If set to 0 you don't have anymore the bombard attack for some units, some ships and artillery.
- DCM_AIR_BOMBING : If set to 0 you don't have anymore the new airplane bombing attacks of factories, ships in harbor and civil buildings.
- DCM_ACTIVE_DEFENSE : Possibly, if set to 0 you don't have units that can bombard that would eventually attack automatically an enemy unit attacking.
No idea what are the other options.
