First up is the Far Avalon game setting. It's not an 'ATU' as such, in that it was created as a setting in its own right, in which you can use the Traveller rules if you like, rather than as a setting for Traveller.
Maybe that sounds like hair-splitting, but Far Avalon was not created using the Traveller rules (we used our own system, more about that later) and some different background assumptions were made. As anyone familiar with my previous work will expect, it's a setting where a small group of adventurers can make a difference and where there is scope for a wide range of adventuring styles.
We're following Far Avalon with several starships and spacecraft books, which are compatible with Far Avalon and other settings using the Traveller rules. These books use the Mongoose ship design system and add a few new concepts as well as providing some different ships to encounter, shoot at or whatever.
We also have two big adventures underway. Counterweights and Measures is completed and in production, and I'm working on Infinity Lost right now. More about those another time.
We also have a rules set in production, named QADVentures (Quick and Dirty Adventures). The world-building book (QADVerse) is done; the core rules need me to find time to add in some fiddly bits. Hopefully I'll get that done by New Year.
Anyway, Avenger is back on the scene. We have product out and a lot more to come. We also have a facebook group:
