The other thing (probably first) is a multiplayer follow-up to HHSOLO 1, with some satirical Black Humor for good measure. Political commentary. Since it seems the way of things, I think my layout will go easier if going forward I just shoot for 6x9 format for everything - this presents both freedoms and constraints, but at least I won't need to retrofit a book down from 8.5x11, again. I think since the demand was high, everything going forward will be paper first, and digital as a bonus or freebie.
The second thing is HHSOLO2, a solo DCC book just for Thieves. Of course, now I know what works and what don't, I won't necessarily limit it to just Thieves, but thieving may be the focus of it. Sure, there'll be a little bit for everybody but you'll not get deep down to the Heart of the Thing unless you're a Thief.
I will work on my 40K table and the Genestealer Cult here and there, as I am able. And I'm running a Purple Planet game biweekly starting a month ago or so, and it appears to be taking of (at least on paper).
