So how may campaign worlds do you use? OK, sure for a specific game, setting, or genre you use something specific but as a go-to setting how many do you use?
Let me explain this a little better. My standard fantasy setting is the world of Zoong. So if I’m just getting the group together that’s the place I go to. And it doesn’t matter which system I use. I’ve ran adventures in this setting with 5E, Dungeon Crawl Classics, Swords & Wizardry, and Labyrinth Lord. And it’s been with mostly the same group of players.
They’ve always had fun. They are already used to the gods, the lay of the land, and some NPC’s. We’ve had the unwritten “rule” that players shouldn’t use player knowledge. Plus there’s no indication which chronological order these campaigns have. Not all of the campaigns have taken place in the same geographic region. Heck, these might be alternate universes. Plus I’ve made changes here and there based on what the players have done and any really interesting things that have happened like Cthulhu hating demi-humans.
It also makes things easier for me as a GM. I don’t have t reinvent the wheel each time. I’ve already got a base to start. And plenty of old notes that haven’t been used yet. I like keeping my notes generic and inspirational rather than detailed. First, I want to have easy ways of importing cool published adventures. Second, you never know when a random NPC catches the players’ attention and becomes important. And third, some times there are world changing events thanks to the PC’s or even a really crazy die roll. Keeping the options open.
