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.
The engine itself has no playable data but there is a converter for Panzer General (DOS version). If you do not own this game, download the package pg-data.tar.gz, which I provide in the sense of abandon ware.
