We have been working on several games (Ben and his compatriots--Bex is the editor, our kids and friends are playtesting) for a few years. The mechanic is basically complete and now it's a matter of attaching all the various gameworld points. However, life has intervened in the lives of all the developers and time is at a premium, so much of it has been put on the back-burner.
On the burner are a fantasy setting, a sci-fi setting, a modern horror setting, a pulp setting, a supers setting, a post apocalyptic setting and a ... hmmm... "everything all mixed together" setting.
It's all at various stages of development and just needs a little impetus on the part of the developers to get them completed.
