Hi, I'm new to FG! Not really, I suppose - I played on FG about 15 or 20 years ago, but I'm effectively new. I suspect that my question is answered somewhere already, but I haven't been able to find it by searching forums, so my apologies if I'm asking a question that's already been covered, and I respectfully request a redirect.
I purchased the Standard License. I'm trying to build a campaign, and I believe that the first step is to load sources. When I attempt to load the DMG, PHB and MM, it appears as if I need to now purchase those, separately. Did I just pay $40 for a game that now needs another $30 or so for every source book I want to utilize?..

Thanks LordEntrails.
My sense on this is that this would be a great feature if it could be incorporated into the 'Use a GUI ruleset builder to build rulesets' request. I upvoted this request in the hope that this would be something that could be included. Even if a full rule-set can't be used, it IS pretty hard to adjust rules without essentially re-writing the entire player's handbook manually (and then handing out new sections to players when they start). It's not the end of the world, but this tweak is one of many that could go into this larger GUI ruleset builder, even if it comes instead as a 'GUI 5e ruleset extension builder'.
