I'm going to be submitting something called "Dead... and Back" at the end of the week. Alien invasion, zombies technological singularity, government created undead ubersoladats, power armor, and other goodness. Of course, that’s just one of the suggested settings.
Actually, I've got about 10 different projects in the works at the moment. I'm slightly obsessive compulsive in case you’re wondering.
For example, in one system your "hit points" also serve as your means to change the world - ie you can trade HP to manifest convenient objects. It doesn't have a name, but the attributes and skills have a clever mnemonic: MMORPG/CLICK. Another is a war game centered around submarines, and a third has to do with Anime style robots.
Then of course, I have Xnoexodous. Its over 200 pages of handwritten notes at the moment, will be about three books when I’m done, and that’s all I’m willing to reveal.
Provided there's some more feedback, additional material for Gangland will be provided. A new version of "Eastern Front" called Great Patriotic War is in the works as well.
