Cinema Tactics offers rules, scenarios and more.
From the rules introduction:
Cinema Tactics is a game of sword fighting, bow shooting, and spell casting in party level fantasy engagements. It can be played with two dice, a deck of playing cards, and a piece of paper. Players lead heroes against forces marshaled by the Overlord or bands of heroes may be pitted against each other.
While these paper miniatures were specifically designed for The Fantasy Trip, they certainly would be useful for any other dungeon crawl or RPG game.
Plastic Legions has some photos of a terrific skirmish battle board of some ruins set aside a sea. Wonderful stuff. I’d love to play a pirate skirmish game on this.
Salvation and Steel is a set of free wargames rules for fantasy skirmishes. The author writes:
Salvation and Steel is a turn-based fantasy skirmish game designed to be played with 28mm miniatures on a 3′ x 3′ board with around 8 to 14 models per side. All materials needed to play Salvation and Steel, including the rules, are FREE or can easily be proxied.
The basic rules for Salvation and Steel aim to keep things relatively simple, and they’ve been written with a big focus on balancing the complexity of unit stats (attributes) and rules, in order to make things tactical and competitive without the players having to rules-check more than play during a game.
Simply put, the basic rules were not only written for new players, but also for younger players wanting to get into miniatures games and do something rather than read about it for longer than 5-10 minutes.
The advanced rules are, for the most part, an expansion rather than a replacement of the basic rules.
Realm of Chaos has some nice scans of dungeon floor plans from Old School Warhammer publications. I have the original of this set in a stack somewhere. I wish GW had not gone so far astray from the things that made it great in the 1980s and 1990s.
