I'm a long time player but decently new GM (I guess it'll be a year with this group this summer, but I still feel quite new). When I played I felt like the majority of what we did was larger story arcs instead of one shots. But now that I'm GMing I'm having a hard time finding written out story arcs (that are finished) and I feel like I must just be failing somehow. I've done all the one shots in the quick start guide, then at PAX last year the Catalyst store had Boundless Mercy, so I picked that up and we ran that (pretty fun all in all, though a few issues, mostly with the strength of enemies at times, and a few missing bits of info). Then after a few random one shots I grabbed Splintered State and ran that (adjusted the beginning a little to not be set up as a starter mission). Now we've finished that and I'm having a hard time finding other complete (or at least complete to a point where its easy to stop and doing other runs until the next installment without it feeling weird) story lines to run. Maybe I'm just bad at searching, but I feel like everything I pull up is either 4e or still being released (like the Chicago missions, or I guess those might be done, I don't really know how to tell, but I can't get them all as one unit). I know there is going to be less for 5e now then there was for 4e at the end of its life cycle, but I feel like I should still have way more options that I'm probably just somehow missing.
Then there are the campaign books (like Market Panic, or Book of the Lost, which isn't quite out yet) that just provide some basic hooks and outlines right? No overarching story? Not that that isn't useful, and I probably need to pick one up at some point, but with limited budget I would prefer to get another full story first then maybe go for a campaign book later. But maybe I'm not fully understanding what they are.
So anyway, just looking for advice/clarification on where to go for larger multi run stories and/or what ones do people suggest (if there multiple).
