LGeneral is a turn-based strategy engine heavily inspired by Panzer General.
You play single scenarios or whole campaigns turn by turn against a
human player or the AI.
Entrenchment, rugged defense, defensive fire, surprise contacts,
surrender, unit supply, weather influence, reinforcements and
other implementations contribute to the tactical and strategic depth
of the game.
