Villains and Vigilantes Revised 2011 - Jeff Dee and Jack Heram
A revised version thanks to yet another of the episodes of historical copyright stupidity and arseholery as far as I can see.
There are a few minor tweaks here to do with the combat system and the example combat in the text is different, no ancient chinese secret super martial artist, but an enhanced tech guy vs a bad, bad teacher. The artwork is different and not as good, either, but it is the system that matters and still a fine game.

The above link is the complete list of post from this blog, updated each week, if you want to browse like that rather than search.
This list is quite long, and has become longer than I ever thought so in the interests of loading speed it is now situated elsewhere.
Similarly I am working on a simple website to browse by author that combines Free SF Reader and Not Free SF Reader that is extremely bare bones now, and can be found at the second URL above.
