Can't fault them for for getting the proofreading/editing done before physical release (especially as the first set of preorder preorders had some shocking ommissions/mistakes)
Better than the first edition Dark Heresy collectors edition: we paid £70, got the book a month before general release, it came with a misprinted map and needed a ton of errata (and they didn't even consider making a digital version for a year or more afterwards IIRC
). This model is much better.
Yes and no. Yes, it's better but it's still not good from a traditional consumer perspective. Games shouldn't be primarily proofread by customers and should instead get multiple passes prior to even a PDF release unless it's a true beta test. It's just the tabletop gaming equivalent of "we'll just patch it later"/fix it in post mentality.
