I was wondering what other rule sets gamers use for their 6mm games apart from Polemos?

At our Club we have been playing General De Brigade and Blck Powder

Black powder or Hail Caesar! depening on th era.

Just starting on a To The Strongest project.

DBA, One Hour Wargames, Throw Me a 6 and HotT.

Currently - in addition to the various Polemos rulesets - DBA, Neil Thomas Wargaming: An Introduction and his Simplicity in Practice rules published in Battlegames magazine, Horse Foot & Guns and WRG 1925-1950 for WW2.

Grande Armee for Napoleonics. Bitter Angels (the Grande Armee variant I am publishing this spring - finally!) for ACW. Commands and Colors for Napoleonics and SYW. 

Currently looking for a rule set for my "big unit" Napoleonics: when a battalion is 24 stands of 3 strips each, and cavalry close to 100 figs each, what rules will work? Looking for something simple. 

ACW  6mm - Altar of Freedom

Later C19th - Bloody Big Battles

Biblical, Ancient and Medieval = DBA 

Fantasy = Im working on my own rules for 6mm fantasy

ACW/Later C19 - Mit Blut und Eisen 

Late C17/Early C18 - Twilight of the Sun King (updated)
