Leipzig was the first of three Napoleonic games by SPI using similar mechanics - the other two being La Grande Armee and 1812 (hex-grid version).
The module provides just the map and counters. You need your own source for the rules and charts (geekmail me if you are stumped).
No image scans are used in the module. The map is scratch-built and echoes the SPI printed map. Counters in the module also mimic the originals, but are made as Game-Piece Image Definitions.
