I pushed some files to DriveThruRPG for the print version of Mini Six today. There's a whole process involved. They have to submit the files to the printer to see if they are okay first. If they are, I have to order a sample. If that's okay then I can activate the title on the site as in-print product.
It's softcover just like the original small print runs.
They are having some sort of difficulty communicating new files with their printer currently, so that might add a few days. It's very likely I've made some mistakes, and if I have I might not be able to fix them immediately. If all goes well Mini Six could be in print again in a few weeks, this time permanently.
At the same time, I have lost some faith in the pay what you want model and have started traditional pricing for it. Thank you to the folks who have purchased it at any price (including free) in the past. Anyone who has it in their DTRPG library will keep it, regardless of any change to the price that I make.
