Your Favourite Rules

Age of Reason for 25mm SYW/AWI - if you don’t look after your flanks and rear you will get into trouble.
Fire & Fury Brigade & Regimental for ACW. Rebasing all my 25mm ACW for Regimental, use 15mm for Brigade.
Age of Eagles for 15mm Naps,  age of Honor for 15mm SYW.

Blackpowder always worked fine for us. Sometimes with a few minor alterations, if consensus could be reached.

Since my club chose 28mm as the scale for BP I didn't play it anymore since the game then clogs up in table-wide lines and maneuverless dicerolling matches.

But played in a smaller scale or on a huge table it is still a fine game.

Black Powder is indeed a fine game, but after playing I always felt I’d played a game of Black Powder rather than a Napoleonic or ACW or Zulu war game. For Napoleonics, I like Lasalle for small battles and Boucher for big ones

Another vote for Maurice, I enjoy the simplicity of it, as well as the degree of customization from the advanced rules and national advantages. Though I am lucky I have the game as I managed to nab it for "cheap" from Ebay, paying over 60€ for a ruleset is a tough ask.

Depends on the size of the game. For big skirmish then Sharp Practice, for larger battles I’ve loved Fire and Fury and there are a few variations around that take it further than the ACW - I’m hoping to live long enough to use it for 28mm Spanish Succession
