Panzerschlacht WWII Rules
Panzerschlacht is a set of free wargames rules for WWII micro armor. The author writes:
This is the World War 2 version of AToS. It uses exactly the same game mechanisms and, apart from the weapon factors, the only difference is that the ground scale has been increased to 1mm = 1 metre to allow for more aesthetically pleasing ranges.
In our games we mark all casualties on the vehicle and figure bases. This allows a paperless game with no book-keeping whatever. By allowing the models to represent more than one vehicle it becomes possible to field an entire panzer division on an eight by six foot table.
WRG 1750 – 1850
Dating to 1972, the Wargames Research Group’s 1750 – 1850 are primarily intended for the Napoleonic Wars. By modern standards they’re a bit dated, but my recollection is that they are fun.
