WRG Napoleonics likewise, their first rule set was awful, but the second lot were fantastic. If you want to command 2-4 divisions plus support, move Bns, set out the light coy, and play a turn in 30-60 minutes they can’t be beat. There are some cleverer abstractions out there but these are the rules I prefer to game with.
Likewise, between my November present of 50 odd figs and Christmas dad took me to what looked at the time like a HUUUGE Napoleonic wargame. Table covered in scenery, troops marching hither and yon, dice rolling. Nothing was ever the same for me.
