This review might be a little premature, because I'm still at that excited-post-download phase when I'm feverishly clicking through the 458 pages.
I'll say again ...
Four-hundred-and-fifty-eight pages of RuneQuest goodness.
This definitely has the look and feel of an older RQ or BRP title. The mechanics and the writing style is very accessible, with the occasional black and white ink drawing.
The rules, setting and atmosphere (with a bent towards ancient, mystical, classical) is generic enough to adapt to different campaigns, whilst providing enough detail for interesting springboard points especially regarding character (and monster) backgrounds, magic, skills, "passions" cults -not to mention the gritty effects of chaos. As well as the dice mechanics, there's plenty of tips and guidelines and optional rules.
I'm also happy to say that it appears to be an "everything-you-need-to-play" publication. (I hate buying supposed "core" books only to find that there's no monster list or many references to "essential" accessories.)
As I type it's still $25 which is a good price for a volume of this size. I'm looking forward to seeing a hard copy -surely it will be a thick tome - so the PDF on a tablet will certainly be more portable for fast rule checking at the table.
Nice work, Design Mechanism! This is a respectable descendent of a noble line.
