Timeline 300 is a set of steam-punkish rules for a now-defunct line of miniatures. The rules, though, can be applied to other figures.
Miniatures Rules
Hail of Fire WWII Rules
Hail of Fire is a set of pay-what-you-want wargames rules for company level games in World War II. The authors write.
“Hail Of Fire” is a company-level, WWII themed miniatures war game designed to be both simple and easy to learn while keeping both players engaged in the action! And best of all, the rules are only few pages long! So print out the PDF, throw some models on the table, and jump right into an exciting tabletop brawl!
Using a fast, interactive turn sequence, players are always in the fight. The addition of hidden action points, fast and easy deployment, and a delayed combat resolution system ensures that both commanders will be fighting the friction and fog of war as much as they are each other!

New Zealand Colonial Wars DBA Variant
Stephen Thomas offers a DBA variant for New Zealand Colonials Wars. The author writes:
These rules are intended to refight the battles of the New Zealand Colonial Wars, 1840-1872. They do not cover skirmishes They are based on DBA, and influenced by the article by Ed White on DBA and the Seven Years War (WI65), and Clive Clapson’s article on the Maori Wars (WI63). As in Ed’s article there are two assumptions:
1. The first round of close combat also includes short range small-arms and artillery fire.
2. Troops potency depended on their ability to deliver close range volleys or cold steel.
