6. Campaign Sourcebook and Catacomb Guide
2nd Edition
1990
The artless cover for some of these books is going to suck, I admit. This books is divided into two parts. The first gives you, the Dm, tons of tip[s on how to run a game. Instead of lots of rules, instead it gives the DM guidelines and info on how to run the best campaigns, create the best worlds, and so forth. Then it actually has runs and tricks on how to create your own world, followed by information about creating maps and stuff. In some ways, it is a better DM’s Guide than the actual DM’s Guide. It’s amazing, and has info from everything from ordering snacks and cleaning up after a gaming session to world build tips. Amazing.
