OGL Steampunk (d20)
A game covering the broad genre of steam-age science fiction¸ using a variant of the D20 System of third edition D&D and D20 Modern. It is¸ however¸ a complete core rulebook released using Wizards of the Coast's Open Gaming License (OGL). - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.

Imagine a world where computers were developed a century before their time¸ powered by levers and steam engines instead of microprocessors; a world where the zeppelin never went out of fashion and new technology made it safer and faster; where brave men and women explore a yet undiscovered world to find the wondrous ruins of lost civilisations; where the mysterious age of magic is slowly fading to usher in an age of cynical reason. This is the world of OGL Steampunk¸ a shadowy amalgam of fantasy and science fiction devoted to marrying the possible with the improbable. OGL Steampunk investigates a fantastical past of magic and myth that incorporates the spirit of progress and exploration and translates it into stories of speculation¸ wonder and excitement¸ a world that might have been¸ had some of the world's key events happened a little differently. Against a backdrop of scientific progress¸ magic is a palpable reality that the heroes of the day must discover and contend with. Cultists seek to awaken the power of ancient races¸ alchemists use arcane formulae to power their infernal devices and creatures of legend walk alongside the human occupants of major cities¸ either adopting the science of the day or enslaved by it. Dare you journey back to the smog-filled streets of a world that never was and yet¸ so easily¸ could have been.
