I agree. Core rule and 100+ page crunch-focus books should always be available in dead-tree format. And if CGL continuously wants to re-print them with revised errata, there will always be new players to buy them. But these upcoming location-concept-crunch mutations... they'd be better served as modular products.
I really hate the idea of these books that don't know quite what they are. They are hard to put together and not feel like someone crammed a bunch of half ass ideas together. Even with a consistent theme. I hear the argument that some people like it because it's a "all in one" option for updated fluff and crunch. However I have to think that that sentiment is a product of CGLs glacial production cycle. If you haven't gotten a new stat block in two years you don't care if it's in the back of the Bogata splat book; alternatively, after two years of running the same sprawl even Bogota can look interesting.
If War! was modular I could forgive it hitting the web s close to Milspec. Bogota splat book with maps and history of the war and detail of the forces, Milspec crunch book with vehicles and gear, and Merc operations/hotspots setting guide in three separate web products. Then later the three come out in single print volume and available compilation PDF with errata and updates to the original files. Everyone is happy, and the publisher gets a whole bunch of selling options that may resonate with players that would otherwise have abstained from purchasing or simple purchased only once.
I also feel that something like that would justify the price CGL is charging for these web supplements. A 40 page supplement for $8? I'd have to go back and check my purchase history, but I seem to recall that Digital Grimoire was only $5. There's a world of difference between $5 and $8, and I can't help but think that a savvy publisher would get more purchases over all with a lower price.
