I don't have access to InDesign, Scribus files would be valuable. I also couldn't open the pdf in Scribus. Information on it is valuable, but it would be easier if I had access to files that I could use directly

Creat tools. Too bad it's only compatable to inDesign CC and not CS6. For small countries such as Iceland the license cost is staggering as there is no monthly subscription and no Adobe support for CC.

Sure, it's a bit of a bother that a lot of this is for Adobe Indesign only, which you're not going to have unless you're a professional, but the included .pdf does have a lot of information about the fonts, headers, etc, that are needed, and it's not too hard to create stuff in other applications. I guess the question is do you value the convenience at $30/month? Honestly, just fidding around with LibreOffice for a few hours gets pretty close, though whether that's publishable on the Foundry is a different story.

The feature I think is lacking is the colours. I had to go to Drainsmith's wonderful dispensary of everything to find the RGB codes for the different blues, orange, red, etc, used in the document. It would be great if they were included in .pdf template.

The images and references on the PDF of the template are useful, but most of what would be useful for people trying to lay things out with it is almost exclusively useable with only Adobe creative suite software. I'm sure it works just fine for professionals, but for most users it'll take jumping through hoops to use the PSD files (they're all in CMYK format, which GIMP at least cannot open), and the InDesign templates are straight-up inaccessible to any other program because they're in proprietary Adobe formats.

It's got a few bits of Android and Terrinoth themed stuff, which is nice, but it's very limited. The images for stat blocks, for example, only appear in the core book version.
