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.

For those of you looking for a different setting (indeed, a different world) for your steampunk games, you could take a look at Steamworld Daleth. The author writes:
Steamworld Daleth is a gothic world on an alien planet. Call it an imaginary country, a geofiction or a follie. During the many years I have worked on Daleth (now over 20 years) the world has become what she is now: a steampunk/gothic world where the echo of the Victorian Age still sounds, but where many odd things are yet to be discovered. It’s a mix of fantasy and reality, a dreamscape of my imagination. Daleth can be used as a setting for the role playing game Intrigue & Illusions, but is not developed as such. Daleth is much more than a mere setting for a RPG. It’s a world with its own dynamics.
