I've been working to introduce steam power into a game setting for a while, and the flavor text in the introduction of this guide was worth the purchase price. The impact of the technology is considered and discussed, giving the GM quite a few ideas to consider in making the choice to add this new technology to a fantasy setting.

Even if the base system isn't d20 based, this guide is worth considering if you're thinking of introducing the technology in your world. Conversion to anther system isn't terribly difficult, and the ideas that can be spawned, not to mention the surprises that can be dropped into a game, make reading the guide worthwhile.

Glad I purchased the material.
