More like 16 months...
And it's been 1 big adventure product per 6 months, 1 small to medium sourcebook per 6 months except the first, but that had the core rules. And 15+ short adventures per 6 months, released through the adventurer's league.
That's actually quite a lot of content. Just much of it is funneled to retailer support programs that get people to the store.
Well, I guess that would be a decent release schedule, but it just seems slower than that. Has it been 16 months? What's the "small to medium" book, the Sword Coast? I still think that's a bit anemic, but I'm willing to see how it goes. Two books a year would be ideal I think, but I would really like to see some short module support. Surely a few adventure paths running over the course of the year should be doable, no? Maybe 3x a year, release 1 part of a 3-module adventure? That's where a lot of our great memories come from, modules. The adventure league stuff I'm not really counting. It's not a bad thing, but that's not what I'm looking for.
PF has a TON of module support...and thankfully, I can covert pretty easily ;oD
